Feasibility Study of Small Computer Application of Multi-Trade Scheduling
Abstract
The Shipbuilding and Repair Industry has long stressed the need for planning and scheduling. Organizations and systems dedicated to this end vary greatly from yard to yard depending upon size, complexity of ship(s), and even customer requirements. This feasibility study is based upon the belief that most yards have highly developed systems for ship construction and ship repair, utilizing main frame hardware and software. These systems are based on yard wide Master Schedules and are oriented to individual ship requirements, therefore, leaving interfacing of multi-ship scheduling to department level solutions. Most trade departments of most yards have solved these Master Scheduling system voids with manual paper work methods, which result in laborious, tedious and tardy data and reports. Man power planning and forecasting is guess work, and emergent work scheduling is managed by crisis. The small computer has reached a very high level of sophistication, but has not yet been fit into the department level, complete with yard wide system interface. Futher to these points refer to exhibits I thru III. The classic flow (exhibit I) differences between shipbuilding and ship repair do not greatly alter the shop trade scheduling objectives and controls. However, overall management is conducted by ship (exhibit II) leaving shop management the problem of integrated item scheduling. The shop management can best be accomplished thru item priorities rather than ship priorities (exhibit III) and a sound system must be in place in order to provide adequate scheduling and control.
