Abstract

This study discusses the optimizing project selection and scheduling problems. In real life, cash inflows and cash outflows of each project are uncertain, we regard them as stochastic variables consequently. Considering time value of capital, Net present value is used as the standard to measure the projects and introduce chance-constraints to control the uncertainty and formulate the model. According to the logical relationship and the characters of projects, we introduce implicit enumeration algorithm to select appropriate projects and schedule them in a reasonable order. Finally, a numerical example is given to express the thought of the model.
