Process chain optimization

Process chain configuration Process chain optimization Process chain redesign... 

In general, dimensioning of manufacturing process chains means its configuration. Thereby, process chain dimensioning is classified in two categories - process chain design and process chain optimization.

The advantages of the LFRT products are offset by requirements to optimize the whole process chain including extruder screw design, processing parameters and mould design, thus needing higher investment and production costs.

Fruit Industry Supply Chains (FISC) are interconnected networks conformed by production nodes (farms), processing plants (fruit packaging and concentrated juice plants), and storage facilities, along with clients and third party raw material and services suppliers. Although Supply Chain optimization is a mature field, very few contributions on FISC modeling with management purposes have appeared so far in the open literature.

As a rule, to manufacture a given component, different process chains are possible, posing the question of optimizing manufacturing processes and subsequently the process chains that should be applied. The first goal is to keep the process costs to a minimum at constant or even enhanced product quality. Another goal is to improve process productivity. Environmental protection, careful use of resources, and use of reproductive materials are increasingly important considerations. 

Within this context, near-net-shape (nns), which involves optimizing the manufacturing process and particularly shortening the process chains, describes one trend in part manufacturing development.

To build up the polyene chains, the (E/Z)- isomers of the C6-unit 19 are produced from the ketone 20 and acetylene (4) in three steps (Scheme 3). Lithium amide is first reacted with acetylene (4) in liquid ammonia and the solvent is then replaced by an ether. The lithium acetylide-ammonia complex 21 thus formed yields, after 1,2-addition to 20 and aqueous work-up, the tertiary carbinol 22. Excess ammonia and acetylene (4) are largely recycled back into the process. The lithium manufacturer can recycle the recovered and prepurified aqueous lithium hydroxide solution. The entire process was optimized with respect to reaction conditions in the 1980s and may be regarded as a model process from the environmental and economic points of view [17]. 

The major focus in the supply chain is to increase operational efficiency in each functional process, but not in an integrated way (e.g., functional optimization instead of supply chain optimization).
