Sustainable Green City Development Project Analysis using the Critical Path Method (CPM) and the Crashing Project Method on Time and Cost Optimization

Due to the increase in population all over world, term city development has emerged using method of sustainable green cities, which are cities designed taking into account environmental impact reduce required input from energy, water, and food production. This study discusses this topic with three main objectives; first is analyze project work network Sustainable Green City Development Project, second investigate speeding up on planning, third determine cost differences before after acceleration. The Critical Path Method (CPM) valuable for managing complex projects if activity durations known. However, reality, projected may vary course a due multiple factors, such as equipment breakdowns, human errors, material shortages. used CPM crashing methods optimal turnaround time critical path optimization techniques. Analysis showed that initial duration was 1205 weeks but can be reduced 1197 weeks. acceleration, there slight difference, corresponding 0.67% decrease approximately 8 total US $55M at normal became $59M increase.
