Material requirements planning device, material requirements planning method, and material requirements planning program

摘要

PPROBLEM TO BE SOLVED: To provide a material requirements planning device operable in conjunction with frequently changing production process schedule progress performance management information and capable of achieving labor saving in material requirements planning work and highly accurate material requirements planning (MRP). PSOLUTION: The material requirements planning device of a type conjunct with production process performance progress automatically acquires production design specification data including material data, daily production process schedule data, production process schedule performance progress data, and material stock data including on-site in-process material stock; and, when working out material requirements planning required for production over the whole production process schedule period, a material stock amount at an arbitrary requirements planning execution time on a day to start requirements planning is used as a reference value, an initial stock amount iz(i) for every material name at the starting time on the day to start requirements planning is calculated and set by adding to the reference value a material consumption z(i) from a requirements planning start time to the arbitrary requirements execution time on the day, a daily material consumption during the whole production process schedule period is calculated starting from the set initial stock amount iz(i), and the material requirements planning is worked out.
