Supply chain management (SCM) has recently received considerable attention in business management literature. Many companies consider a well-designed SCM and implement it to their systems to increase the performance of production systems. Supplier selection is a fundamental aspect of SCM, which heavily contributes to the overall supply chain performance. SCM is a complicated decision-making problem including both quantitative and qualitative factors. In this paper, we try to determine criteria, indicated by experts for selection of suitable suppliers. The proposed study obtains weight of each criterion by Fuzzy Linear Goal Programming (FLGP) technique. We rank the suppliers by Fuzzy Quality Function Deployment (FQFD) method. The study is executed for a PETROCHEMICAL Co. to evaluate and select the best suppliers.
In this paper, we presents an inventory problem where initially, a retailer purchases Q(=P+R) units and after fulfilling the backlogged quantities, there is a P unit of the on-hand inventory. It continuously declines to meet the customer’s demand, which depends on the on-hand inventory level up to the time t = t1. After that the inventory level declines by constant demand up to t = t2. Thereafter, shortage occurs and it accumulates at the rate ?(T-t) till t = T when the next batch arrives. This whole cycle repeats itself after the cycle length T. The proposed model of this paper is investigated under various conditions and the implementation of the proposed model is presented through some numerical examples.
Management teams are always expected to provide transparent financial reports for public. Different characteristics such as honesty, conservatism as well as management capability may play essential role for the success of businesses in supply chain. The proposed study of this paper considers the effects of three factors; namely management capability, management honesty and management conservatism on quality of financial statements. The proposed study collects the information of 92 firms from Tehran Stock Exchange over a nine-year period from 2004 to 2012. Using some statistical tests, the study has concluded that only management honesty could influence on quality of financial reports. In our study, conservatism did not have any impact on the quality of financial reports and it seems that managers have to take more risk in order to reach financial objectives.
Activity based costing (ABC) is a new age accounting system developed to overcome the limitations of traditional costing system, which in today’s technologically advanced world has lost its ability to provide accurate and useful cost information often required in taking various managerial decisions, like setting of selling price, ascertaining profitability of products as well as customers, taking a make or buy decision, eliminating the non-beneficial activities, and rewarding the employees. In this paper, an ABC model is developed for a government hospital in the state of Bihar in India to quantify its various public health related services. Although, there are limited published research papers related to application of ABC model in a specific department or method of a healthcare system, none of them has investigated its scope for organization-wide implementation. The results obtained from the developed ABC model in the public hospital would provide more comprehensive and accurate cost information, and radically contribute to the hospital administration in effective planning, controlling and decision making. This paper also elucidates about various obstructions and difficulties encountered during the implementation phase of ABC model in an Indian healthcare setting.
Customer relationship management (CRM) systems track and measure marketing campaigns over different networks. There are literally many studies associated with the implementation of CRM in different industries. This paper presents an empirical investigation to determine effective factors influencing on the success of CRM implementation. The study designs a questionnaire in Likert scale on measuring various factors and distributes it among selected employees who work for the biggest software maker firm in city of Tehran, Iran. Using principal component analysis, the study has detected five factors influencing on the succes of CRM including customer relationship technologies, customer oriented, enterprise development strategies, customer services and business plan.
Procurement risks analysis is a crucial study in supply chain risk management. According to the phenomenon of snow ball effect, if a risk occurs at the primitive node between buyer and supplier, it will be strengthened and extended throughout the entire network. Hence, it can have more disruptive influences comparing with risks that happen in further nodes. In this paper, through a case study, the most important risk factors and its multi-dimensional consequences in procurement risk analysis is derived from the literature review and implementing a Delphi method that takes into account the nine risks factors and 39 preliminary variables as risk consequences. The nine risk factors are limits of global communication, packaging and transportation, procedures and standards, sanction, supply of equipment, price of equipment, Communication, management of technology and delivery mistakes.
During the past few years, operations research applications in health care operation management have grown quickly. On the other hand blood as a perishable, valuable and lifesaving product is one important asset of any healthcare center. Therefore, designing a blood supply network comes to importance. It also should be noted that a blood supply chain comprises specific modifications. This study intends to locate blood bank components in a network, and to determine the allocations among the network components. The supply chain components considered in this study are donation sites, testing and processing labs, blood banks, and demand points. It is known that demand centers such as hospitals and clinics highly depend on blood products and any deficiency in procurement can even result in a person’s death. Thus, in the last layer of the considered network a transshipment sub-network is considered between demand points. Most of the intricacies in problem formulation of blood supply chain are regarded in this study; cases such as blood wastage, blood product decomposition in lab facilities, and transshipments between demand points. Due to the fact that for such an important and lifesaving supply chain the aim would go beyond minimizing cost, another objective function is presented for the problem. Hence, to obtain a Pareto solution for both objective functions ?-constraint method is utilized. Finally, to demonstrate the applicability of the problem, the model is implemented on a number of problem sets.
For today’s high competitive market, when immensity purchasing of inventory becomes convenient or obligatory, to discover an alternative market in order to maximize the revenue earned is a tradition. In this paper, we considered an inventory model for seasonal products with Weibull rate of deterioration having two potential markets, say, primary and alternate. To handle the inventory up to the next season will result an increase in total cost. So it is a favorable task to transfer the remaining stock to the alternate market even at a slightly differ in selling price. Solution procedure, numerical examples and sensitivity analysis for different variables are presented to illustrate the model.
This paper presents a supply chain management by considering efficiency in the system. The proposed study considers two objective functions where the first one maximizes the efficiency of the supply chain and the second one minimizes the cost of facility layout as well as production of different products. In order to measure the relative efficiency, the study uses the method developed by Klimberg and Ratick (2008) [Klimberg, R. K., & Ratick, S. J. (2008). Modeling data envelopment analysis (DEA) efficient location/allocation decisions. Computers & Operations Research, 35(2), 457-474.]. The study has been formulated as a mixed integer programming and the implementation of the proposed model has been demonstrated using some numerical example. The preliminary results indicate that it was possible to increase the efficiency of supply chain without increase the supply chain expenses.
