Today various firms benefit from TPM, quality techniques and systems in order to improve performance levels of their production processes. Using each of such approaches individually could not ensure the survival or growth of organizations. In this article, the relationship between maintenance, quality and performance of production systems has been described. Also, recent scientific innovations on integrative models of TPM with quality techniques and systems, such as TQM , JIT , TQC , EFQM , LETQMEX , etc. are demonstrated. Advantages and limitations of the integrative approaches are other issues, which are discussed. With respect to the conclusions derived from the article, it seems that TPM is the necessary basis for achieving ultimate objectives of the production systems, and due to its close relationship with quality techniques and systems; it should be adopted neither separately, nor individually.
Soft power as one manifestation of power allows countries to gain influence through means such as po-litical values, cultural diplomacy, and foreign policy attitudes. Iraq has become a venue for influential players such as Iran and the US to exert their soft power after 2003. Iran employs shared religious ties with the Shiite population in Iraq, promotes its independent anti-imperialist foreign policy as a value, highlights the shared geography and historical memories between the two countries, and applies other similar elements to enhance its soft power. On the other hand, the United States employs cultural attrac-tions and promotes values such as freedom, democracy, and human rights. The United States presents itself as an idealistic democratic archetype and encourages Iraq to emulate its model in the post-Saddam era. The aim of this chapter is to provide a comparison of soft power status of Iran and the US in the post-Saddam Iraq. © 2024, IGI Global. All rights reserved.
This chapter delves into the impact of artificial intelligence (AI) on the educational systems, spanning both schools and universities. The primary components of an educational system include students, teachers, monitoring and evaluation (M&E), and administrative organization. While there are undoubtedly other components, these mentioned items are the most crucial. Artificial intelligence significantly influences all of them. In this chapter, the authors thoroughly examine and analyze the effect of AI on each of the four educational components, employing a systematic review and library methodology. Consequently, after the introduction, the chapter is organized into four parts, corresponding to each component. The main finding indicates that AI technology has revolutionized education by offering personalized and adaptive learning, flexible teaching, as well as smart administration and swift assessment systems. This chapter also highlights the drawbacks associated with it. © 2024 by IGI Global. All rights reserved.

E-business as one of the ICT infrastructure has experienced a high growth in last three decade, such that the approach and planning of the organization to enter the global market and attract the new customer has been affected in this regard. However the application of E-business in commercial activities requires attention to a range of internal and external factors affecting it. Due to these factors and planning businesses for optimal use of e-business technologies these appliances not only will ensure the success of the operation but also it can provide the business growth. One of the items that may be affected by the implementation of e-business is the structure of the organization. Following the changes in the organizational structure, many other fields will be changed in the organization. One of the most important fields is the role and responsibilities of mangers. In this paper the impact of implication of E-business in three factors of organization structures including controlling, standardization of integration and centralization of the role of middle manager position will be reviewed. © 2015 IEEE.
Global issues such as environmental disasters, malnutrition, poorness, international economic inequalities, local and ethnic conflicts, migration phenomena, globalization paradoxes, and other crises and challenges are so complex that governments and traditional diplomacy cannot tackle them alone. Therefore, diplomacy has expanded beyond the monopoly of governments. One of these new forms of diplomacy is citizen diplomacy or "people-to-people diplomacy." This can involve NGOs, private peacemakers, scholars, or other "bridge builders." Citizen diplomacy takes many forms, such as student/faculty exchanges, church programs bringing conflicting groups together, or cultural/scientific/sporting events that allow disputants to interact cooperatively or competitively. The informality of citizen diplomacy activities gives it a high degree of flexibility. This research aims to demonstrate the effectiveness and importance of citizen diplomacy in today's world, and its role in maintaining peace at the global level. © 2025 by IGI Global.

The Network Design Problem has been studied extensively and in many of these models the cost is assumed to be a concave function of the loads on the links. In this paper we investigate under which conditions this is indeed the case for the communication networks. The result is presented as a theorem, the Concavity Theorem, and a list of conditions that can easily be verified. It is also shown how the theorem can be extended to other applications, like in the area of road transportation.

In almost all of the existing resources of failure mode and effect analysis (FMEA), "severity" is being determined from the designers' point of view, not from the customers' side. In this paper, a new approach is proposed to enhance FMEA capabilities through its integration with Kano model. This evolves the current approaches for determination of severity and "risk priority number" (RPN) through classifying severities according to customers' perceptions. It supports the nonlinear relationship between frequency and severity of failure. Also a new index called "correction ratio" (Cr) is proposed to assess the corrective actions in FMEA. The findings of a short case study highlight the gap between managers and customers in prioritising a set of failures and the difference between RPN and Cr prioritisations, caused by target failure frequencies. The proposed approach enables managers/designers to prevent failures at early stages of design, based on customers who have not experienced their products/services yet. © Emerald Group Publishing Limited.

Let R be a non-commutative ring. The commuting graph of R denoted by Λ (R), is a graph with vertex set R \ Z(R), and two distinct vertices a and b are adjacent if ab = ba. In this paper we investigate some properties of Λ(R), whenever R is a finite semisimple ring. For any finite field F, we obtain minimum degree, maximum degree and clique number of Λ(M n (F)). Also it is shown that for any two finite semisimple rings R and S, if Λ(R) ≃ Λ(S), then there are commutative semisimple rings R1 and S1 and semisimple ring T such that R ≃T × R1, S ≃ T × S1 and |R1| = |S1|. © 2004 Elsevier Inc.

This paper proves that if G is a graph (parallel edges allowed) of maximum degree 3, then χc′(G) ≤ 11/3 provided that G does not contain H1 or H2 as a subgraph, where H1 and H2 are obtained by subdividing one edge of K23 (the graph with three parallel edges between two vertices) and K4, respectively. As χc′(H1) = χ c′(H2) = 4, our result implies that there is no graph G with 11/3 < χc′(G) < 4. It also implies that if G is a 2-edge connected cubic graph, then χc′(G) ≤ 11/3. © 2005 Wiley Periodicals, inc.

A critical set in an n×n array is a set C of given entries, such that there exists a unique extension of C to an n×n Latin square and no proper subset of C has this property. For a Latin square L, scs(L) denotes the size of the smallest critical set of L, and scs(n) is the minimum of scs(L) over all Latin squares L of order n. We find an upper bound for the number of partial Latin squares of size k and prove thatn2-(e+o(1))n10/6≤maxscs(L)≤n2- π2n9/6.This improves on a result of Cavenagh (Ph.D. Thesis, The University of Queensland, 2003) and disproves one of his conjectures. Also it improves the previously known lower bound for the size of the largest critical set of any Latin square of order n. © 2005 Elsevier B.V. All rights reserved.

Since customers are not all created equal, it could not be overemphasised that a precise knowledge of Customer Requirements (CR) holds the key to business success. This paper offers Customer Requirements Segmentation (CRS) as a novel technique for categorizing CR with precision. CRS involves three different types of segmentation according to: service encounters or the service provided within each service encounter (CRS-I); customers' characteristics, e.g. age, gender, etc (CRS-II); and prioritized CR importance (CRS-III). Starting with a comprehensive list of Service Quality Dimensions (SQD), the CRS-I, II and IIIs will successively emerge. Although Quality Function Deployment (QFD) has been widely used in analysing and eventually delivering what the customers want, its implementation has not always been effective. CRS would help overcome some of the major difficulties in QFD implementation which are particularly acute in the Service Sector, namely: in ascertaining the ambiguities in the voice of the customer (VoC); in handling large houses of quality (HoQ); and in resolving conflicts among different variety of CR. A case study on using CRS to analyse the service encounter at the front desk of a four-star hotel will be presented in order to demonstrate CRS in action. The implications of the findings are discussed in detail.

Purpose - The purpose of this paper is to enhance understanding of corporate governance (CG) in delivering excellence in corporate social responsibility (CSR). Design/methodology/approach - The paper demonstrates models of CG and the associated elements affecting CSR. It addresses the integration of CSR into management systems through a framework as a process-based management system and studies the role of leadership style for socially responsible organizations. The paper develops a comprehensive questionnaire that enables organizations to audit their commitment to environment and social responsibility. Findings - The paper reflects that CG encompasses different internal and external factors, by which management of organizations are influenced. This is also compatible with the new corporate community models, in which investors, the public, customers, employees and associated corporations have a mutual impact on management. The leadership style is also found to play an important role in socially responsible organizations. In this respect, transformational leader seems to be more effective, compared with manager and transactional leader. The paper suggests that organizations should audit their CG capabilities towards CSR, based on a proposed questionnaire in order to drive excellence in CSR. Originality/value - The paper provides a comprehensive study to help understand key elements of CG and CSR and proposes a new questionnaire to organizations for assessing how far they are able to move towards socially responsible organizations. © Emerald Group Publishing Limited.

Previous research has not been conclusive as to whether people prefer different or identical allocation principles in distributions of positive and negative outcomes. Thus, in this study, the question of whether or not group goal accounts for preferred allocation of positive and negative outcomes was posed. As hypothesized for division of surpluses, the results showed that relationship-oriented goals predicted preferences for equality, whereas performanceoriented goals predicted preferences for equity. Moreover, the results were the same for allocation of deficits. This suggests that people implicitly have different orientations, or goals, in mind in group situations that similarly influence the way they prefer to allocate positive and negative outcomes. The results also showed that participants allocating deficits deviated to a larger extent from the allocation principles than did participants allocating surpluses. © Society for Personality Research (Inc.).
International Journal of Productivity and Performance Management (17410401) 56(3)pp. 226-240
Purpose - The purpose of this paper is to provide an integrated approach that prioritizes organizational key performance indicators (KPIs) in terms of the criteria of SMART (Specific, Measurable, Attainable, Realistic, Time-sensitive) goal setting. Design/methodology/approach - The research was carried out using the analytical hierarchy process (AHP) technique as the basis for pairwise comparisons of SMART criteria, considering each KPI. Findings - A new approach is outlined, encompassing step-by-step guidelines for decision makers to conduct the prioritization process of SMART KPIs. The results of the case study highlight the applicability of the proposed approach and the calculation process for prioritizing KPIs. Research limitations/implications - The rating scales used in the AHP analysis are conceptual; although it identifies which dimensions require improvement, the proposed approach does not provide guidance on an appropriate action plan to address deficiencies; another limitation is that the framework adopted only the SERVQUAL service dimensions. Originality/value - This paper gives a novel approach for prioritization of KPIs. The proposed approach has a holistic mechanism; it could empower decision-making teams; it is capable of enhancing advanced quality engineering approaches; and provides great opportunities for future research. © Emerald Group Publishing Limited.
Scientia Iranica (23453605) 15(5)pp. 652-660
In this paper, a new approach to formulate a class of scheduling problems is introduced, which can be applied to many other discrete problems with complicated structures. The concept of graph circular coloring is applied to develop a model for the special case of an open shop scheduling problem. In this problem, there are some independent jobs to be processed in a shop with dedicated renewable resources. Each job consists of several tasks with no precedence restriction. Each task is processed without preemption. The processing time of the tasks is given. Processing each task requires using some multiple specified types of resource, while no more than one task can use each resource, simultaneously. Some tasks can be shared by more than one job and the process may be repeated more than once. The objective is to develop a schedule which yields the minimal makespan length of all jobs, as well as the number of cycles. The model is first developed for cases when the processing time of each task is one unit and, then, it is generalized by relaxing this restriction. In both cases, a circular coloring formulation is shown in comparison with traditional formulation (single process execution) results in an improved makespan and also the required information regarding the optimum number of cycles to repeat the process. © Sharif University of Technology, October 2008.

Design for Six Sigma (DFSS) is a powerful approach for designing products, processes and services to meet the needs and expectations of the customer while driving down quality costs. It involves the utilisation of powerful and useful statistical tools to predict and improve quality before building prototypes. This paper attempts to study DFSS and the associated experiences of world-class companies. For this purpose, DFSS methodologies are introduced and compared with Six Sigma methodology. The DFSS process is demonstrated and some examples of world-class companies are presented. Finally, some implementation obstacles are addressed and the DFSS training programme is described and emphasised. The findings imply that the methodologies for DFSS are enormous and companies employ different methodologies. Also, it has been found that the role of project leaders is essential for the success of projects and the training programme offered in DFSS should be flexible.

This study aims at providing an explanation of Electronic Human Resource Management (E-HRM) and introducing its activities and tools. Furthermore, we investigate the effect of various independent variables such as job satisfaction, professional commitment, organizational commitment... on the effectiveness of HRM as a dependent variable. For this purpose, by cluster sampling from Iranian HR managers, 110 of them were chosen to participate in this study. Then, research hypotheses were examined by deploying multiple linear regressions to the data gathered from specially designed questionnaire. Findings indicate that E-HRM tools are rarely used, however, according to the experts' judgment if they are used, they would have a positive effect on the HRM output in Iranian organization. Finally, a model for assessing the effectiveness of HRM was proposed.

Security is very often mentioned as one of the preconditions for the faster growth of e-commerce. Without a secure and reliable internet, customer will continue to be reluctant to provide confidential information online, such as credit card number. Moreover, organizations of all types and sizes around the world rely heavily on technologies of electronic commerce (e-commerce) for conducting their day-to-day business transaction. Providing organizations with a secure e-commerce environment is a major issue and challenging one especially in Middle Eastern countries. Without secure e-commerce, it is almost impossible to take advantage of the opportunities offered by e-commerce technologies. E-commerce can create opportunities for small entrepreneurs in Middle Eastern countries. This requires removing infrastructure blockages in telecommunications and logistics alongside the governance of e-commerce with policies on consumer protection, security of transactions, privacy of records and intellectual property. In this paper, we will explore the legal implications of e-commerce security governance by establishing who is responsible for ensuring compliance with this discipline, demonstrating the value to be derived from information security governance, the methodology of applying information security governance, and liability for non-compliance with this discipline. Our main focus will be on analyzing the importance and implication of e-commerce security governance in developing countries. © Springer-Verlag Berlin Heidelberg 2008.
Economic load dispatch is one of the most important problems in power system operation, therefore the aim of this paper is to establish a method to reduce electricity generation costs with a new approach. This method introduces two new constraints called rate of change of frequency (ROCOF) and minimum frequency as the main constraints in economic dispatch in this paper. This approach reduces emission and fuel costs of the power plants as well as transmission line losses. Therefore, this method has also the capability to control frequency in a desirable range. Finally, the proposed method is simulated on a test system. In the simulation, the economic load flow with is solved with spinning reserve, transmission lines loses and generation constraints as well as the two new mentioned constraints, i.e. ROCOF and minimum frequency constraints. Simulation results obtained from the proposed and conventional methods, show advantages of proposed method. ©2008 IEEE.
TQM Journal (17542731) 20(1)pp. 68-86
Purpose - The purpose of this paper is to propose an integrated model of quality function deployment (QFD) and customer relationship management (CRM) for design and delivery processes. Design/methodology/approach - After the literature review, the elements of a CRM business cycle were integrated with different phases in QFD. The proposed model was further developed, based on customer participation in the design and delivery of products/services, as a major stage in CRM in three cases: customer participation in design; delivery; and design and delivery. As a case study, the customer participation in delivery was studied in after-sale services of the Iran Khodro Co., which is the second major carmaker company in Iran. Findings - The results imply that QFD and CRM are complementary approaches and once they are combined, their capabilities are enhanced and managing customer relationship is empowered. According to the case study, personnel monitoring and human resources management (HRM) have been targeted as the first priorities in process parameters and process control characteristics, respectively. Research limitations/implications - Although the developed model involves considerable advantages, due to the different matrixes used for QFD, its use might become time consuming and complicated. Also, gathering information from customers and categorizing them respectively play major roles in effective and strategic CRM. Originality/value - The proposed model provides a means of harnessing the power of the present research innovations and advancements in order to empower customer need assessment, acquisition, development, equity leverage, retention and referrals, as well as prioritization of the features of products/services, processes, and performance indicators, according to the voice of customers. © Emerald Group Publishing Limited.

A In this paper, an attempt has been made to provide a comprehensive perspective of the integrative approaches and frameworks. For this purpose, the subjects of lean and Six Sigma have been demonstrated separately and compared, and then their integration approaches and frameworks have been studied and discussed. The outcomes imply that integrating lean and Six Sigma creates a win-win situation. The combination of both can provide the philosophy and the effective tools to solve problems and create rapid transformational improvement at lower cost. Potentially, this could increase efficiency and effectiveness, which in turn leads to higher performance. Copyright © 2008 Inderscience Enterprises Ltd.

In everyday life, people often encounter situations where their personal interests are at odds with the welfare of a larger collective to which they belong. What seems to be an individually rational choice may later have detrimental effects on the wellbeing of the group. Such conflicts of interest are referred to as social dilemmas (Dawes, 1980). Social dilemmas are formally defined as situations in which (1) individual outcomes for non-cooperative behavior or defection are larger than outcomes for cooperative behavior (favoring the collective interest), regardless of how other members in a collective behave; but (2) if all members adhere to this individually rational behavior, all members will acquire a lower payoff in the end as compared to if all had chosen to cooperate in the first place. © 2008 Springer US.

Today's economic climate characterised by increasing competition and structural turbulence will require a higher combined level of productivity and quality than has been the case in the past. This paper has demonstrated the interlinkages among quality and productivity, and for this purpose, similarities of the two important concepts have been reviewed. Major quality factors, which are the possible sources for poor/high productivity have been introduced, and finally, some advanced models have been presented and developed in which, the direct and indirect relationships between quality and productivity are addressed. This study has also highlighted the fact that improving quality plays a fundamental role in increasing operations productivity in organisations. Copyright © 2008 Inderscience Enterprises Ltd.
