A Case Study: Salient Features Of PPUS)
1. Millions of chip-implanted parts move around in a complex production system of construction under the scheme of PPUS
2. Glue Logic is the controller system in the PPUS which is used to Orchestrate the Movement and Alteration of chips
3. Glue Logic is designed to make building manufacturing work control, easy and flexible. This system binds Multiple-Application Software Modules, referred as “Agent”.
4. The Glue Logic consists of two major parts: 1. The communication interface subsystem 2. The data management subsystem
5. The communication interface exchanges information with agents running in both the same work-cell controller and remote work-cell controller connected with the network system

Their scheduling elements are necessarily intermingled and linked with each other. The whole schedule is managed and adjusted as one giant flow of processes. One small change in a tiny part of the whole schedule may possibly propagate its influence into the whole. Every such complex system, which is likely nonlinearly linked often, shows some chaotic behavior at worst and leads to a catastrophe. Upon this peculiar condition, construction process management is conducted on site holistically at every moment from the commencement and completion of a project.
There are variety of causes that force scheduling change. It is of critical issue when a signal of change is dispatched within a complex system. If timing gets lost, disastrous consequence may result with severe cost loss. It is also critical where a change occurs among multiple players as well as what happens. The Parts and Packets Unification System (hereafter called PPUS) allows parts or units to signal change in their attributes as they go through the complex production …show more content…
First, PPUS is viewed from a parts maker’s point of view. Activities of building parts maker are engulfed in a much larger complex whole of activity network on site. A maker manages its production process and responds to changes required from the larger flow. Some changes often propagate their influence on multiple subcontractors who are linked to each other and
Cause loss of cost among them, potentially, at worst, resulting in exponential blowout. We identify the points in process where outbreak of cost increase is likely and then set them as production gates. The main stream of a maker’s process comprises of Contract, Design Approval, Manufacturing Preparation, Product Drawing, Production Plan, Manufacturing (cut, fabricate, assembly, and curing), Shipment, Installation, and Delivery. The sub process from Design Approval to Shipment is solely within the maker’s process, which remains a black box for the construction site. However, this sub process is one of primary sources of cost increase. The Glue Logic system monitors and supervises the sub process by
