Abstract
Companies keep minimal resources such as equipment, labor, and non-renewable materials to maintain productive working capital. This means that resources are constrained, and a multi-project environment adds further complexity since resources have to be shared among projects. Existing project management approaches such as critical path method (CPM), program evaluation and review technique (PERT) etc. are mainly suitable for the unconstrained resource situation. However, industry practitioners are required to handle resource constrained situations and multi-project priorities. Hence, it is important to identify the best practices and systematic approaches used in resource constrained multi-project environment. The objective of ongoing research is to determine the industry practices under resource unconstrained and constrained multi-project settings. An interview with experts and a questionnaire survey were conducted to determine the current industry practices followed for solving project scheduling problems. This research has revealed that resource unconstrained multi-project environment is rare, whereas resource constrained multi-project environment models the real nature of actual projects. When modelled as an unconstrained resource problem, underutilization of resources might occur. On the other hand, in a resource constrained problem, limited resources are shared among project sites, resulting in efficient utilization of resources. The decision process can follow either centralized or decentralized model. A decentralized model is recommended for handling small size projects in a multi-project environment. However, the systematic centralized model is recommended for the large size multi-project environment to optimize the multiple objectives. This study brings out that the current industry practices in India to manage multi-project scheduling problems use_experience based heuristics to accommodate the practical challenges which may not be replicated in other project instances. © Advancement of Construction Management and Real Estate, CRIOCM 2017.All right reserved.
