摘要

In any job, project, program, or complex undertaking there exists a need to understand all aspects of the work. This understanding is necessary to satisfy all requirements in the most effective and efficient way. The methods available to plan and accomplish these tasks are as vary as much as the tasks themselves. They range from job shop techniques to Material Requirements Planning (MRP) to Project-Based Management Information System (PBMS) to continuous manufacturing. This paper is a critical analysis aimed at classifying two of these system approaches as they relate to the ship repair equation. Material Requirements Planning (MRP I) tracks a need for material through a project. The production process on the material determines how labor is applied to transform raw materials into finished products. MRP material needs are determined by sales forecasting; while requirements are determined algorithmically from material take-offs. Another form is Manufacturing Resource Planning (MRP II). This form of MRP is a management process, supported by computers, which results in monthly production plans based outlooks, etc., and is far sales more comprehensive in scope and integration than MRP I.
