A mixed integer programming model is formulated to define the problem clearly and a few valid inequalities are deduced to strengthen the model. Some properties and two upper bounds of the problem are proposed. Based on these inequalities, properties, and upper bounds, a heuristic solution approach with two improvement strategies is proposed to resolve the problem and the numerical experiment demonstrates that the proposed solution approach is effective and efficient.<\/jats:p>","DOI":"10.1155\/2015\/745378","type":"journal-article","created":{"date-parts":[[2015,3,18]],"date-time":"2015-03-18T18:07:56Z","timestamp":1426702076000},"page":"1-8","source":"Crossref","is-referenced-by-count":27,"title":["Modelling and Optimizing an Open-Pit Truck Scheduling Problem"],"prefix":"10.1155","volume":"2015","author":[{"given":"Yonggang","family":"Chang","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Shenyang University of Technology, Shenyang 110870, China"},{"name":"ChinaCoal Pingshuo Group Co.
