11. Under the STR/OP sequencing priority rule orders with the jobs with the longest STR/OP are run first. True False 12. The LCFS and Johnson’s priority rules are basically the same except LCFS uses due dates as a major determiner of job sequence. True False 13. Johnson’s rule a priority rule used in sequencing production jobs is used only in production situations where we are dealing with one machine or one stage of production activity. True False 14. The objective of Johnson’s rule for job sequencing is to minimize flow time from the beginning of the first job until the completion of the last job. True False 15. The assignment method of job sequencing is a special case of the transportation method of linear programming. True False 16. A shop-floor control system is a system that uses data from the shop floor as well as data processing files to maintain and communicate status information on shop orders and work centers. True False 17. One of the principles of work center scheduling is to match work center input information to what the worker can actually do. True False 22. One of the principles of work center scheduling is that while certainty of standards routings and so forth is not entirely possible in a shop certainty should always be an objective to work towards. True False 23. One of the principles of work center scheduling is that the effectiveness of any shop should be measured by speed of flow through the shop. True False 24. One of the principles of work center scheduling is that once started a job should not be interrupted. True False 25. When work is scheduled in detail using the setup and run time required for each order then theoretically all schedules will be feasible. True False 26. Scheduling hourly work times using the “first hour principle” insures that no excess labor will be used during the work shift. True False 27. MES and SES are acronyms for “Manufacturing Environment Scheduler” and “Service Environment Scheduler” systems respectively. True False
