We probably can say all people that are familiar with industrial engineering, have some information about supply chain management. Of course some people have more information about it and some have less. However, it is expected that they have some information about logistics because logistics is one of the most important elements in supply chain management. But it is sure that they have no information or less information about reverse logistics. That is why I have chosen this subject as my thesis. I have presented an optimization model with a numerical example  

In spite of logistics outsourcing benefits, Iranian companies usually do their logistics activities themselves, and logistics outsourcing are limited in performing of transportation and warehousing. One of the main reasons of these conditions is lack of a powerful and modern 3PL in Iran even though there are high potentials for 3PLs in Iran’s different industries such as automotive, oil and petrochemical, food and grocery, retail goods and etc. Therefore formation of powerful and modern 3PLs in Iran is necessary. Two styles for formation of 3PLs are common. In First style the companies start up directly the third party logistics business and in second style traditional logistics firms try to... 

Proficient management of Supply Chain (SC) necessitates an efficient evaluation of SC performance. This highlights cardinal role of performance measurement in management of SC. However, SC has multidisciplinary nature in its wide spectrum of activities including planning, control and coordination of intra- and inter-firm players from upstream suppliers to downstream customers. As such, performance measurement of SC is a quite complex task and an effective assessment can significantly help enterprises in achieving their business goals. Objective of this study is to provide a comprehensive structural framework to facilitate assessment of various aspects contributing on SC performance.... 

Last decade witnessed a virtual explosion of information about customers and their priorities. This information gives some potentials to companies that increase their revenues, especially when new technologies make the possibility of changing prices with low costs. Simultaneously, companies had large development in dynamic management of supply chain in both internal operations of companies and their communications. Although pricing decisions have some effects on operations, but integration of operations and marketing are very common subjects in science and business. In this thesis, we consider the integration of dynamic pricing and ordering in a supply chain. Then, we present a dynamic... 

The subject of this thesis is a two-echelon inventory system with a manufacturer and multiple distribution centers (DCs) that satisfy the demand originating from multiple sources. Demand from each source follows an independent Poisson process. The transportation times between the manufacturer and the DCs are assumed to be positive which may require keeping inventory at both the warehouse and the DCs. Inventory in both echelons is managed using the base-stock policy. The manufacturer works with
M/M/c product system. The cost of demand fulfillment for each DC consists of inventory holding and backlog costs. The objective is to determine the optimal base-stock levels at the DC  

Nowadays the concept of competition in business has been expanded from enterprises to supply chains. For success in this competitive environment, it should be established complete coordination and synchronization between different rings of the chain in both strategy and operations. The supply chain management is a factor for achieving to this purpose. Effective supply chain management, especially in complex supply chains like petroleum upstream supply chain, requires to strategic factors that propel the chain to the long term goals. Unfortunately, it is showing off the vacancy of attending to this case in the literature. This thesis tries to fill this gap in literature with a new approach... 

Business intelligence is a set of theories, methods, processes and technologies that are used to obtain useful and meaningful information. Due to the inclusion of different and various products, chain stores have to manage a lot of data, which is different from the retail and company data in terms of number and variety. in this regard business intelligence has to be used for making decisions. The catch is felt in different parts of the chain stores. The main purpose of this study is to provide a model to investigate the impact of using business intelligence on Ofogh Kourosh chain stores. Research variables were extracted using literature review on the impact of business intelligence on chain... 

This Project describes a new model for Inventory management in Supply Chain (SC), based on Fuzzy Set Theory and Echelon Inventory model. In today’s changing market, managing the Supply chain inventories, especially for the new product becomes more complicated and uncertain than before. This work provides a new approach to model uncertainties involved in supply chain management using fuzzy set theory. For achieving a more realistic model, Echelon Inventory is used as the base of integrated supply chain inventory model. In proposed model, some of input parameters like demand, production parameters, transportation time between inventories, and some of variables like lead times are described as... 

In recent years, Supply Chain Management has become one of the most desired concepts for Industrial engineers. In this thesis, specifically, one of the SCM’s aspects, Joint Economic Lot Sizing1, which in literature have been studied by various people with different viewpoints, is considered and a two-stage supply chain facing certain demands is studied. These demands are changing as a function of selling price determined by a supply chain and the goal is to increase the chain’s total profit in comparison of individual policies in which members decide about their profits separately. The optimal amount of selling price varies end-customer demands exponentially and leads to changes in economic... 

Inventory problems are studied for a long time and many authors have investigated models with shortage phenomenon. To reduce inventory holding cost or decaying items we can have a shortage period in witch a part of demand is backordered; Although we pay fines to pending costumers, as shortage period is extended a larger portion of them will refuse to wait until replenishment. So, calculating an optimal duration for on hand inventory and shortage period with respect to inventory costs has became an interesting research field. However, related studies are rarely appeared in supply chain researches, where an integrated inventory model for a supplier and a retailer is proposed; especially when a... 

In the last two decades, Supply Chain Management has become an integral part of sciences such as Management and Industrial Engineering. A key issue in this concept is how to coordinate the activities of the members of the chain in order to improve the performance of the whole system. In this thesis, the main concentration is on production, pricing and lot-sizing policies in a two-stage supply chain with a producer and a retailer. The producer manufactures the final product and vends it to the retailer, and the retailer sells it to the final customer. The customer’s demand is under iso-Elastic pattern that is one the four most popular price-sensitive demand functions. Moreover, in attempting...

This research deals with a supply chain consisting of one vendor and several retailers. Every retailer orders a fixed discrete quantity in fixed discrete time intervals. Order quantity and order cycle of each retailer could be different from the others. The vendor orders the required quantity to a supplier to fulfill the received demands. Also the vendor orders a discrete quantity, which will be immediately received at the vendor’s warehouse. In this supply chain system, the lead-time is assumed to be zero and shortage is allowed for vendor. The aim is to find minimum vendor’s inventory cost. We proposed a backward Dynamic Programming algorithm for the model. The algorithm creates vendor’s... 

The integrative supply chain management is one of the main business processes between final consumer and supplier and it is formed by responsibilities such as production, services and information those have added value for customers and beneficiaries. Therefore and as the goal of a chain is maximization of gained value for the factors involved in chain, so, this goal can be more accessible by decreasing transportation (transportation method, tracking, …) and stock costs (conservation, ordering, …). As its purpose, this thesis intends to introduce and increase the options of goods transportation possibilities between retailers’ warehouses and evaluation of its effect on transportation and... 

Nowadays, increasing of difficulties in production and procurement conditions such as competitiveness among manufacturing firms, variety of products, rapidly changing of customer tastes, shortening of product lifetime and complexity of demand forecasting on one hand, and key role of consumers and deteriorating products on countries revenue on the other hand, make replenishment policies of deteriorating products challenging and also interesting for both researchers and corporate managers.In this dissertation several novel models on replenishment policies for deteriorating products are proposed under uncertainty by the help of single or multi objective mathematical models. One important... 

Tile and ceramic industries plays a vital role in Iran’s economic due to significant added value and to be indigenous concerns. Therefore, in recent years huge investments have been performed by non-governmental agencies in this industry. In spite of high value of investment in this industry, efficient and updated management requires to reach the maximum output of the industry’s potentials. However, in recent years, supply has been exceeded of the demand in national markets. Moreover, the existence of the well-known abroad brands in the international markets has leaded to sever competition’s environment of this industry. In this circumstances, tile and ceramic companies to take the... 

This research is focused on inventory management of a blood banking system by assuming deterministic demand and supply with the objective function of minimizing the summation of shortage and wastage. In this research, two integer programming models are developed to solve the problem. In the first model, it is assumed that the blood groups are independent, but in the second one, the transactions between different blood groups are allowed, as it is in reality. Then, to be more efficient and practical, a dynamic heuristic algorithm is developed. In addition, we compared the solution of heuristic algorithm with the exact solutions derived from integer programming models. The data used in this... 

Supply Chain is a complex system and its modeling generally results in complicated mathematical problems. Solving these problems, one should make assumptions that make solutions impractical. Knowledge-based frameworks such as ontology has been proposed for tackling this issue. In this thesis, with relying on a seven step ontology developing method, UML as development language and Rational Rose as development software environment, an application ontology for supply chain and its problems has been developed. Furthermore, with use of a Benzene, Toluene and Xylene supply chain as an instance, it has been shown qualitatively how to use the ontology in various supply chain problems. It is... 

This paper studies a multi-product, multi-period, multi-allocation hub location problem based on real case in domestic automotive industry. As 3PL companies spread, using dynamic hubs in a contractual manner becomes passible; So in this paper the hub set is the combination of both static and dynamic hubs. The nodes are suppliers, sites and dealers of a supply chain that have certain demand of each product in each period. In this problem backlogging is allowable and causes penalty. Different transportation modes like road and railroad are usable just in hub network. Direct transmission is possible and candidate hubs are capacitated with multi suggested capacities. A mixed integer programming...
