Deliverable Factors of Manpower Requirement Plan: An Evidence from Indian EPC Company

Abstract

Abstract-: This paper discusses the manpower plan required, and their deliverables factors to the clients of an Engineering Procurement and Construction in the process of designing for the construction of a thermal power plant, analyses the resource usage versus the planned allocated scheduled resources, resource levelling of scheduling. As a part of resource availability constraints in a critical path, method calendars were used to postpone activity start time, extend the activity duration that resulted in an increase of the project duration. A method of a forward pass has been proposed with the help of the Scurve diagram interpretation with the application of DMADV approach for resource levelling is illustrated with an activity-on-node as a case and a precedence diagram method. This research has elucidated on the critical issues of resource constrained levelling in the application domain of the project management in anticipation of deliverables from its employees to an EPC company. The findings of this research would provide useful inputs for the vendors and the consulting firm.Keyword-: Critical method, Manpower planning, Resource levelling, S-curve I. INTRODUCTION Project management necessarily demands a reasonably structured succession of processes. The structured process is of utmost importance when considering a project organisation. The basis of control is made only by an organised and a planned method that represents the scope of work, resources required and financial plans. The project managers need to develop a schedule for directing and controlling resource of workers, machines and materials in a coordinated and a timely manner in order to deliver the project within the stipulated timeframe set by the client. It is fact that with the complexity of the project, the project managers use related to project management software's like the Primavera Project Planner and M.S Project for analysing and scheduling using the critical path scheduling method [1]. The critical paths usually represented as CPM entails a forward pass to determine the total activities, the total duration for each of the activity involved with the Earliest Start Time (EST), and the Earliest Finish Time (EFT) for each of the activity and the resource assigned to the activity. The forward pass is ensured by the backwards pass for calculating Latest Finish Time (LFT) and Latest Start Time (LST) and Total Float (TF) for each activity. Total Float is defined as the maximum time that a delay could happen to complete the activity without disrupting and/or changing the total duration or total completion of the project. The activity with zero total floats are the critical activities of the project. The CPM scheduling under resource limits constraints is generally referred to as resource allocation, which reschedules the project tasks based on the CPM analysis without resource limits constraints such as finite resources are efficiently utilized while keeping the extension of project duration to a constant [2]. Implicit resource driven, finish to...
