// this method builds the neighborhood around the anchor (anchorpispips) given as input
|
//
|
// this consists of
|
// 1 upstream supply chain of anchor
|
// 2 downstream supply chain of anchor
|
// 3 of the neighborhood obtained thus far we search upstream along already selected langelegs ( so side products of step 2 can be properly supplied)
|
// In step 1 we look at unit periods that are bottlenecks, if applicable we add
|
// 4 neighborhood to debottlebeck a random set of those unit periods ( consists of upstream + downstream around the bottlebeck - the latter only search along existing planning)
|
// 5 We then inspect the neighborood obtained so far and for a limited set of pispips where pre production is used ( put stuff in inventory end ) we similarly build
|
// a neigbhoorhood to debottleneck that
|
// Finally ( and if there still is room) we go through the procedure of adding friend pispips to the anchor
