Implementation of integer programming in decision support system for operational optimize procurement of public bus transport distribution (Case study: Trans Jogja)

Abstract

Trans Jogja is a public transportation for traffic's problem solution. The fact, trans jogja have many problem for balancing supply and demand. These problems have impact at reducing public interest. optimizing the operational cost of the fleet is one method to solve this problem. Linear programming is a method for optimalization in riset operation. The steps in this method are determining the function objectives, variables, parameters and constraints, then making the structure models for procurement decision makers operational of the bus using linier programming. Variables, parameters and constraints are Obtained from bus service indicators in one route base on World Bank 1986 and Land Transport Department indicators. The output of this research is the decision support system for operational optimize procurement of buses for Route 1A, 1B, 2A, 2B, 3A, 3B to help the distribution amount of buses in each route Effectively, efficiently and can reduce operational cost. These features system are of the fleet amount, bus capacity, load factor, the bus interval, average speed, reserve buses, passenger number, operational cost Whose value can be changed According to the current situation then there is distribution feature amount of buses in each route.
