Selection of suitable site for constructing coke plant by AHP and ranking method

Coke is a solid and refractory material that remains from coal tar, residual oil and other carbon materials after carbonization practice. With advances in metallurgy industry and upgrading techniques in oil industry, characteristics of coke to produce anode electrode changed dramatically and today petroleum coke become the primary material of many industries. The major uses of petroleum coke is in the aluminium and the steel industry. Selection of a suitable location for the construction of a coke production plant affects from various factors which these factors have different aspects such as environmental, technical and economical. Various factors may overlap or conflict with each other. Some of the important factors for choosing an appropriate location are: being closed to the source material, feed capacity and assigning it to the coking unit, feed quality, proximity to markets and domestic consumption, etc. Because the most important raw material for petroleum coke, residual oil, is obtained from refineries, the most basic parameterin the site selection for construction of coke plant is locating near the refinery. To select location for construction of the coke plant, managing these parameters should be in such a way that the plant has the economic and technical justification. On the other hand, in order to establish priority places on base of Iranianrefineries, many properties should be studied. Multi-criteria decision making provides this possibility that differentplaces be prioritized, according to multiple criteria and characteristics. Variability of multiple criteria is a problem in using multi-criteria decision making. Thus, using a software application programming based on algorithms by a suitable method is necessary. In this paper, places priority for construction site selection of a coke plant has been examined by using two methods of AHP multiple criteria decision making and ranking implemented in Matlab software. Thus management of any number of places can be prioritized by regarding each criteria to be classified as managers and professional priorities
