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.
The varying conditions of the sale market and unknown factors affecting the success of candidates make decision making of issuing the distributor license an important matter for organizations. For this reason, the organizations attempt to use techniques and tools for decision making in order to enhance the process of issuing selling license. For this purpose, industrial engineering tools and techniques provide effective aids for managers to have a better work prioritization and planning. One of such techniques is the analytical hierarchy process (AHP) which is one of the multiple attribute decision making approaches. In this study, after determining the important and effective criteria, a model is proposed for the evaluation of the distribution candidates. AHP is used for evaluation of the proposed model, in which the determined criteria are classified in five categories, and then, weighted. After the computation of each criterion for the candidates, the evaluation results are derived. The proposed model is applied and validated in the Paak Dairy Company as a case study. The outcomes imply that the priorities derived from the proposed approach are based on a holistic and precise analysis. Moreover, the use of this approach and changing the decision making priorities might lead to considerable savings in cost and time consumed.

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.

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.

Strategies for improving the patient discharge process have a beneficial effect on many hospital activities. The main objective of this research was to analyse the discharge process at Kashani Hospital in Esfahan, Iran in the fall of 2004. This study took the form of a case study in which data were collected by questionnaire, observation and checklist. SPSS and Operations Research (O.R.) methods were used to analyse data. The results showed that the average time for patients to complete the discharge process was 4.93 hours. The hospital personnel involved identified the main factors affecting average waiting time as patients' financial problems and distance between different wards. The longest hospital stay was 5.7 days in the Neurology ward. Findings showed there was a queue in completing medical records at the nursing and medical equipment stations.

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.

Iran's Small and Medium Enterprises (SMEs) have been widely introduced in the market these days. In the emerging trend of electronic data interchange, Iran's political, economical and social issues have been diverted to a more aggressive approach to the world of e-commerce, that despite the shadowing issues of the past, Iran already internalized the promising craft of e-commerce through various IT adoption techniques and skills. In line with this, this study is aimed to the growing emergence on Iran's SMEs and how e-commerce contributes to the success of IT adoption. (Ajdari, 2007). This paper would further identify the ways and reasons how Iran thrived to its current status as a raising e-commerce country (Powers and Carvar, 1990) It's the main responsibility of governmental forces to enable organizational and national forces to gain dynamic control over resources and markets for a better e-Commerce take off (Moor & Benbasat, I996). Also, we will investigate fifty SMEs and surveys along with personal interviews will be conducted to locate findings, reasons, causes and effects in this regard. Study will focus on three main areas of SMEs including organizational, environmental and technological aspects. Results indicate the significant perceived value of government support in SMEs development in Iran (Dearing, 1990).

This paper attempts to develop a method for readiness assessment of potential electronic commerce (e-commerce) success of Iran's insurance industry. This method can expand in other industries. Key factors impacting e-commerce are identified from Wells, D. and Thomann, j. (2006) researches. This model is a twodimension 3*4 matrix. Each dimension consists of variables that influence on insurance industries readiness. These variables on horizontal dimension are: People Readiness, IT Readiness, and Business Readiness and on vertical dimension are: Business Imperative, Executive Sponsorship, Development Method and Business Process Orientation. Each cells of this matrix evaluated by 5 questions. This research's data are collected via a 60-questions questionnaire-based survey from Iranian insurance companies. At the end of the research, the Iranian insurance companies were strongly recommended by us to invest on e-commerce and einsurance area.
