The four categories of suppliers in Fig. 9.8 are based on highAow values of these variables. In terms of procurement, suppliers in categories D and A have high and low priority, respectively. Suppliers in B and C categories have medium priority. These categories are explained, next. 

Supplier partnerships or alliances have been used to control the cost of procurement. They are based on methods developed in Japan, initially in the automobile industry. These methods have been extended into the process industry and for the purchase of such items as compressor trains. Generally as originally conceived, they were intended mainly for commodity items. By using some innovative approaches, the concept of partnerships or alliances has been extended into the purchase of custom equipment. 

Included in this element are requirements for purchasing documents (specifications, drawings, and purchase orders), selection of suppliers, inspection and control of received material and record-keeping. For ESH/PSM, this element would focus on those aspects of the procurement process which support purchasing according to regulatory requirements, safety standards, risk management controls, etc. 

Electronic marketplace/E-commerce In addition to the many databases available and person-to-person contacts, E-commerce in plastics has been conducted through suppliers web sites or the dot-commerce independent web sites that link material buyers with sellers in transactions or auction formats. During the year 2000 five plastic producers/suppliers and various elastomer producers/suppliers created a new and important business model of a joint-venture web site. It provides multiple companies to join forces to do business. This is a strategy some observers call competition and others regard as just another form of selling in. an electronic format. Regardless of how it is perceived, the model will help propel e-commerce into the mainstream of processor procurement due to the size and wealth of the companies involved. The plastic model example is the largest online business-to-business site todate. 

Step 1 Cytotoxicity. Each polymer was evaluated, at least twice, in blind experiments, according to their toxicity toward insulinoma cells. For many polymers alternative suppliers and molecular weights were also tested. In total 37 polyanions were obtained of which 23 were systematically evaluated. By comparison, 29 of the 36 polycations procured were systematically tested. The results of these experiments are provided in Table 4.

Procurement covers all company and/or market-oriented activities that have the purpose to make objects available to the company that are required but not produced (Large 2000, p. 2). Other terms found in the context of procurement are strategic sourcing, purchasing, supply management and/or supplier relationship management. 

Two basic procurement functions exist for resale or purchasing for consumption or conversion (Dobler et al. 1977, p. 4). Procurement is a core function of the business (Dobler et al. 1977, p. 5). Key objectives in procurement are to procure specified objects at a defined quality from suppliers, achieve cost savings and minimum prices for these objects and ensure continuous supply and foster joined innovations with suppliers based on contracts and a supplier relationship management.

In analogy to the demand side, procurement contracts are fixed by quantity and price with the objective to ensure a basis volume of raw materials. Spot procurement supports company s flexibility requirements and the company can decide the spot procurement quantity with certain flexibility around the offered quantity. Price levels for contracts and spot business differ and are volatile in each period. Typically, companies operate with few key strategic suppliers for a respective product or raw material. Therefore, price-quantity models like in sales planning are less applicable. More often is the case that specifically commodity-type raw materials are procured on many-to-many exchanges, which is out of the scope in our case as described in section 3.2.6. If products are supplied by internal business units, transfer prices are applied following the contract procurement principles.
