Nowadays to keep pace with the global competition, organizations tend to build a long-term relationship with the vendors. As a result, the direct and the indirect consequences of poor decision-making become more severe. There are a lot of methods to determine the best matched supplier for a particular product. In this study, at first, we have calculated the weighted values through MCDM process (Using AHP) for the different product for different vendors. Then we have proposed a vendor selection model using Integer Linear Programming (ILP) Model for multiproduct, multi-vendor environment. The research is intended to build up a generic model to be utilized in different scenarios in the decision making process according to the company’s own preference. We check the validity of the model with a case study for managing the best suppliers for knit fabrics of a renowned textile industry of Bangladesh.

bstract- Automatic street light control system is used in modern world for energy savings by using Light dependent Resistor (LDR).Nowadays the human has not enough time, and he/she is unable to find time even to switch the lights on or off. This new system can be used more effectively in case of street lights. In proposed system, the street lights will be switched on just before the sun sets and are switched off the next day morning when there is sufficient light on the road. The proposed model also uses motion sensor to control the intensity of light. Huge power is consumed when most the vehicles don’t move during the late. This paper shows that the proposed System is relatively low cost, efficiency is better than the existing system.
