Supply and Production/Distribution Planning in Supply Chain with Genetic Algorithm

2. Literature Review

Previous researchers came up with different models on supply chains, to which we came across during the course of literature review. These models can be categorized as:

• •

  Coordinated model of buyer-seller

• •

  Coordinated planning model of production-distribution

• •

  Coordinated planning model of production-invention

• •

  Model of location-allocation

• •

  Coordinated model of purchase-production-distribution

Chandra and Fisher (1994) proposed a coordinated planning model of production and distribution, in which products from a single production unit are transported to retailers directly from the plant. Significance of this model is the demand of retailers for each product in the specific period, however; this also minimizes the total costs consisting manufacturing, transportation and the inventories. Jayaraman and Pirkul (1998) presented yet another coordinated model of mixed zero-one programming. In this model, the input of the production plant are varied i.e., raw materials are supplied from different dealers and the output of finished goods are carried to different storages or distributed to markets based on customers’ demands. This model also aims to minimize the total costs including deployment, operation and storage, production and distribution. In a separate research, Jayaraman and Pirkul (2001) also proposed the PLANWAR model, showing the location of plants and storages with capacity constraints.
