Abstract：The customization feature of mold product has allowed a great number of mold companies to utilize the project management methods for their production management. For the problem that optimal solution of mold project scheduling is hard to be obtained due to a large number of concurrent projects, random arrivals, limited resources and impacts of random events, the simple and effective classical priority rules were employed to get the approximate solution. To evaluate the performance of different rules, 15 priority rules which are suitable for mold project scheduling problem were selected and corresponding simulation experiment was designed based on randomly generated instances with the evaluation index of cumulative tardiness days, cumulative tardiness cost and cumulative tardiness project number. Experimental results show that the optimal rule will vary with the project environment and decision objective. The obtained conclusions are not only valuable for selecting reasonable priority rule to make scheduling decisions, but will also serve as a basis for the construction of effective mold project control strategy based on multiple rules combination.
