Alfares King Fahd University of Petroleum and Minerals, Dhahran, Saudi Arabia KeywordsAircraft industry, Optimization, Personnel management, Saudi Arabia AbstractThis paper describes an actual aircraft maintenance labor scheduling study. The study's objective is to determine the optimum maintenance workforce schedule to satisfy growing labor requirements with minimum cost. The main recommendation of the study is to switch from a five-day to a seven-day workweek for aircraft maintenance workers. A new integer programming formulation, used to obtain an optimum seven-day work schedule with no increase in workforce size, is presented. In comparison to the existing five-day schedule, switching to a seven-day workweek is expected to produce savings of about 13 per cent, or $100,000 annually. 1. Introduction During the summer of 1997, a study of aircraft maintenance worker schedules was conducted at the aviation department of Saudi Aramco in Dhahran, Saudi Arabia (Alfares, 1997). The objective was to evaluate the current fixed-wing aircraft maintenance worker schedule, and come up with recommendations for improvement, if needed. The specific aim was to determine the optimum work schedule that satisfies increasing maintenance labor requirements with the minimum cost and highest efficiency. Saudi Aramco is the main oil company in Saudi Arabia, and the largest oil company in the world. It is in charge of all phases of the oil business, from surveying and exploration, through producing and refining, all the way to marketing and distribution. Because oil revenues constitute the major part of the national income, the importance of the company to the Saudi industrial development cannot be overemphasized. The aviation department is responsible for the air transportation of the company's workers and equipment to remote areas, such as oil fields and exploration sites. The aircraft maintenance division of the department must ensure the safety and airworthiness of the company's large private fleet, which in 1997 included 13 fixed-wing aircraft and 19 helicopters. The fixed-wing flight line maintenance
