Abstract

Estimate activity duration, is a process in Project Schedule Management whose output will be Input to develop schedule process. The accuracy of the estimated duration of the activity is an important point in accuracy of the project schedule in general. Case study on production facility PT. ABC, pump packaging company. They set the desired delivery accuracy level at least 95% (−5%), so it is necessary to develop a new duration estimation system that is integrated between resources (labor, equipment and availability of area/Space) that can be translated into resource capacity, to be used in a more accurate estimate activity duration method. The duration estimation approach in previous studies used and or developed with common methods, including three-point estimation/PERT, analogy, parametric, expert judgment. Several studies also use new approaches such as anchoring method, competency-based duration estimation, duration specification limit duration and estimate activity duration with productivity influence approach. This study proposes development of a new method of estimate activity duration with capacity-based resources. With categories, labor resources, equipment resources, material resources and new variables of location/space resources which are then translated in to resource capacity. The methodology used is archival analysis and statistical analysis for secondary data as well as expert validation questionnaires for primary data on implementation methods, preparation of Work Breakdown Structure (WBS), define activity, estimate activity resources and estimate resources capacity. Simulation of estimate activity duration using monte carlo with heterogeneous of resource capacity. The study resulted implementation method with 10 (ten) processes, 6 (six) WBS levels consisting of level 1 projects, level 2 work groups, level 3 consisting of 13 sub-work, level 4 work packages, level 5 with 83 activities and level 6 with 87 resources that have been entered in 83 activities. Labor resources were identified 13 types, equipment resources 19 types, material resources 30 types and location/space resources 13 types with their respective capacities have been analyzed. Simulation Model with monte carlo can be presented with resource input parameters and provide forecasting project activity duration with standard error <0.001 days.
