Conceptual Framework of a Simulation-Based Manpower Planning Method For Construction Enterprises

The authors put forward an idea of a technique to support labor force need planning planned for construction professionals. The building and construction business experiences scarcities of knowledgeable labor. The approach assists in evaluating the possibilities of project-to job resource sharing and uncertainties in the flow of brand-new orders, both characteristics of construction. Construction contractors' manpower planning is based upon a production plan. An exact and deterministic strategy is possible just for a short preparation horizon covering a fixed set of obtained orders. New orders are won irregularly, and the type and quantity of work they involve doubts. For this factor, the authors argue for using a simulation model of the company's production plan. Such a strategy facilitates mapping the irregularity in the number of orders, their start dates and delivery times, in addition to workloads. Simulating the circulation of potential orders helps evaluate the degree of utilization of the enterprise's human and the impact of the size of employment on the timeliness of the execution of individual jobs. This offers a basis for identifying affordable work levels. The method assists determine the need for manpower and provides the information necessary in the procedure of staff development and recruitment. Moreover, it provides a tool for evaluating the expediency of utilizing in-house resources to fulfill brand-new orders and the requirement to work with subcontractors. The novelty provided in the article is the method of manpower planning in building and construction companies, making it possible to take into account threat conditions in getting new orders and the irregularity of construction process execution times due to factors disturbing the work circulation. The principle of the approach was the basis for the advancement of a simulation design of the construction business's order execution under random conditions, permitting for the examination of the effects of maintaining different levels of employment of the labor force in regards to the degree of utilization of the production potential and timeliness of individual jobs. Thus, the outcome of the research is a tool supporting the choice making of building supervisors in human resources management practice.
