Case Study at Mikuni Corporation

Initial Situation

  • Every production stage is planned individually.
  • Excess inventories of unfinished and semi-finished products are kept in an attempt to minimize waiting times in the production process.
  • There is a lack of overview and possibility to calculate production throughput time.

Advantage with Asprova

  • Priorities are considered in the planning process.
  • Simple Processing of Changes in Work Instructions within the Resource-Gantt-Chart
  • Simultaneous Planning of Multi-Stage Processes

Achievements with Asprova

  • Process Coordination throughout Various Production Departments
  • Shortened Throughput Time of One of the Core Products from 11 Down to 8 Days
  • Establishment of a Production Standard as well as Required Production Time
  • Decreased Work-in-Progress and Excess Inventories by 33%

Manufacturing processes consist of three phases: Casting, machining, and assembly. The assembly stage is controlled by the central planning system, while machining and casting processes are planned individually by their respective departments. This leads to conflicts in communication and coordination, increased inventory stocks, and unreliability across departments as to when a processed part can be expected.

The only solution in sight is the Asprova production scheduling system - this is clear from the beginning, because it is the market leader in Japan! After implementation, the entire factory is planned for centrally. Work instructions issued help in synchronizing processes and eliminating bottlenecks, as well as vastly reducing excess inventory stocks.
