In aerospace and other hi-tech industries with job shop and project processes, end items manufacturing is very important stage of a supple chain. A proper managing end items manufacturing is one of the main condition for effective manufacturing and supply chain management and performance. 

Timing and optimization balance is the key condition for best possible manufacturing and supply chain management and performance. Timing of end items manufacturing and other stages of a supply chain stages is the basis for supply, manufacturing and delivery. Besides, timing determines inventory dynamics and influence manufacturing and supply chain performance. Furthermore, timing accuracy and efficiency predetermines a utilization of manufacturing and supply chain resources. If, when maximum possible accuracy, schedule of end items manufacturing is suboptimal, then we have maximum possible resource utilization and better deliveries simultaneously.

One should note the following. The well-known models, methods and tools for manufacturing scheduling and existing systems for manufacturing and supply management, enterprise resources planning declare opportunity of meeting demand effectively, fast and on-time. In the essence, as we have discovered, they are not able to effectively combine manufacturing and supply chain timing and optimization. 

Traditional approach to meeting demand on-time when promised to customers “needs” backward scheduling. However, this approach does not allow us practically to optimize manufacturing schedule or to make it in a way to provide best possible timing, cost, inventory and deliveries. The well-known tools, methods and systems for forward scheduling are bottleneck and local optimization minded.

On the whole, the existing models, methods, tools and systems for manufacturing and supply chain management cannot schedule end items manufacturing in a way that allows us to obtain best possible manufacturing and supply chain performance. As a result we have bottlenecks, idles, worse cost, inventory and deliveries. 

Long-term research and work for and with hi-tech industries allowed us to find a more effective combination of timing and optimization for end items scheduling, supplying, manufacturing and delivery. This approach was developed and utilized in a form of a management technology for job shop and process environment. This technology is based on system manufacturing management optimization, forward scheduling and timing, effective solution of new system optimization problems and allows us to improve cost, inventory and delivery simultaneously.
