Abstract

This study discusses how to use integrated marketing channel in order to reach the marketplace with lower cost or more profit, and how a framework for analysis can improve the channel decision made by an executive acting as a channel manager or designer. This paper also proposes a manufacturer-distributor-retailer deteriorating inventory system that contains three levels of normal marketing channel. In order to achieve long-term benefits and global optimum of the system, the different facilities should develop their partnership through information sharing or stratgic alliances. The mathematical model describes how the integrated approach to decision making can achieve global optimum by Genetic Algorithm(GA) method.

Abstract

The responsibility of todays's reputable company are not only financial, but also corporate social responsibility(CSR). With regards to the environmental aspect, the public expects green logistics solutions. This paper focuses on how a third party logistics provider(3PL) might provide green logisticsservices through actions that foster sustainability. The methodology used is an in-depth interviewing approach, which described green logistics through the key drivers using depth interviews. An existing conceptual model is used to support our concepts and ideas. Finally, we discuss out the key factors from respondent regarding how to maintain sustainability through action, from 3PL's perspective. We also discuss the benefits and challenges to green logistics in future.

Abstract

This paper proposes a n-manufacturer-one- distributor-n-retailer single-period inventory model for deteriorating items that integrates three levels of distribution system. In order to achieve long-term benefits and global optimum of the system, the different facilities develop their partnership through information sharing and strategic alliances. The mathematical model describes how the integrated approach to decision making can achieve global optimum. Due to the complexity of the non-linear problems, it is not possible to find the global optimum analytically. Annealing is the physical process of heating up a solid until it melts followed by cooling it down until it crystallizes into a state with perfect lattice. Following this physical phenomenon, a Artificial Intelligence methodSimulated Annealing (SA), has been developed to find the global optimum for a complex cost surface through stochastic search process. A computer program in C-language has been developed for this purpose and is implemented to derive the optimum decision for the decision maker. Numerical examples and a sensitivity analysis are given to validate the results of the system. The proposed model has potential application in product distribution inventory systems.
