Automating cost estimating systems

Abstract Interest in Cost Estimating Systems (CES) has grown rapidly in the last few years. The availability, flexibility, speed, and accuracy of micro-computers have provided the impetus for automation of many indirect activities. Central to the successful automation of the cost estimating function is the relative ease with which the user can customize the application software to a unique set of materials, machines, and methods of the organization. Once customized to his particular application, cost estimating software must be easily adaptable to future business changes as well as changes in the cost estimating technology itself. This paper describes the development of a CES which provides a highly productive and flexible approach to user customization. The paper includes an explanation of the system's extensive data and program structure. It is capable of accommodating future technological changes resulting from the introduction of engineering work centers with CIM capabilities. The paper concludes with an illustration of its application to a highly diversified aerospace firm.
