Terms and definitions• Planning

To find suitable goals and operations to fulfill the gap between desires and facts, by clarifying their well-formed structures and parameters

• SchedulingTo clarify relationship among production items and manufacturing resources in the time horizon,considering various constraints and objectives

• APS (Advanced Planning and Scheduling)a system architecture of planning and scheduling

integration to dynamically and synchronously achieve

the goal of each manufacturing enterprise

Introduction of PSLX Consortium Japan

What is PSLX

• Reference Architecture for APS software development

Ontology model (PSLX-04)

Top level objects• PSLX domain objects are ontology in

representing interface arguments• Each data schema of practical systems

can be generated by this object model• Generating operators are:

– create subclass, divide class, merge class, create attribute class, create relation class, add/delete attribute, move attribute through class relation, add/delete relation, restrict multiplicity, add constraints, change name according to PSLX common dictionary

Sub classes• item -- resource, product, material, wip, subas

sy• resource – equipment, tool, labor, ws, shop, s

ite• feature – stock, load, capacity, location• event – start, end, halt, resume• operation – fabrication, transportation, storag

e, inspection, setup, maintenance• party – customer, supplier• calculation – cost, profit

Industrial Applications• Project 1-A (started in Aug 2002)

– Resource booking system for a mechanical fabrication manufacture

• Project 1-B (started in Aug 2002)– Stock information sharing with a 3rd tire

automotive parts supplier

• Project 3 (started in Sep 2002)– Web based supply chain planning for one of the

kind production

• Project 2 (started in Nov 2002)– Remote maintenance using MES and scheduler

integration

Summary

How to use PSLX• Package vendors develop their software

product for shop floors, e.g. scheduler, according to PSLX standard

• ERP vendors make their database schema using the PSLX domain object model, and clarify the mapping processes.

• System Integrators develop mapping modules to integrate PSLX software and legacy systems.

Benefit of PSLX for APS• Schedule can be viewed graphically from diffe

rent places outside the factory• Planning and Scheduling Problems of differen

t business components can be federated• Manufacturing execution systems can be dev

eloped with a common interface for schedulers or shop floor software.

• Many kind of integration with ERP will be dynamically available for floor level management.

• APS system has more design flexibility by using scheduler as a connectable component
