Productivity and Task

Productivity improvement is the primary objective of the plastics processing industry and developments include the entire process. The results of these developments have been implemented in terms of the utilisation of plastics waste, additives and machinery. The role of plastics processing management has expanded, from simply executing to implementing, and requires industries to continue to provide and develop efficient systems and techniques. Improvements are driven by respective solutions to process problems and tbe development of productivity can be achieved by implementing further waste reduction, which is the primary aim of the processing industry.

The quality of decisions, product, and task is improved if group members offer different perspectives, disagree, and seem to introduce conflict into the process. The trick is to manage the apparent conflict well. 

Product-oriented techniques are characterized by product formation, task formulation, and the objectives pursued. Product-oriented tasks vary considerably, according to the multitude of products and tasks. A few examples of these techniques and technique groupings are presented later in this chapter. 

The involvement of workers in quality improvement and innovative development of products and tasks represents another critical ingredient to the improvement of the working environment and to worksite climate, and this, in turn, has been of importance to OH S in the large industrial corporations. Examples from Japan, Germany, USA and Scandinavia bear witness to this (Oxenburgh, 1991). 

Plasma fractionation is unusual in pharmaceutical manufacturing because it involves the processing of proteins and the preparation of multiple products from a single feedstock. A wide range of unit operations are utilized to accompHsh these tasks. They are Hsted in Table 3 some are common to a number of products and all must be closely integrated. The overall manufacturing operation can be represented as a set of individual product streams, each based on the processing of an intermediate product derived from a mainstream fractionation process (Fig. 1). 

Bina System. The first task is to examine the characteristics of the 2-propanol-water-phase equiUbria (VLE, LLE, SEE) to determine the compositions of interest and any critical features. 2-Propanol forms a minimum boiling a2eotrope with water (80.4°C at 101.3 kPa (760 tort), 68 mol % 2-propanol). The a2eotrope is between the feed and the IPA product and is a distillation boundary, thus it is impossible to obtain both desired products from any single-feed... 

Before setting about the task of developing such a model, the product development process requires definition along with an indication of its key stages, this is so the appropriate tools and techniques can be applied (Booker et al., 1997). In the approach presented here in Figure 5.11, the product development phases are activities generally defined in the automotive industry (Clark and Fujimoto, 1991). QFD Phase 1 is used to understand and quantify the importance of customer needs and requirements, and to support the definition of product and process requirements. The FMEA process is used to explore any potential failure modes, their likely Occurrence, Severity and Detectability. DFA/DFM techniques are used to minimize part count, facilitate ease of assembly and project component manufacturing and assembly costs, and are primarily aimed at cost reduction. 

Depending on the product and sales arrangement, the revenues calculation can take from a few man-hours to many man-months of effort. For instance, determining the price for a synthetic fuel from coal can be done in a very short time, based on the cost of service. However, if the price is tied to the price of natural gas or oil, the task becomes very difficult, if not impossible. On the other hand, determining the sales growth and selling price for a new product requires a great deal of analysis, speculation, market research, and luck, but projections can be made. 

Contract review is but one of the tasks in the contract acquisition process. These are marketing, prospect acquisition, tendering, contract negotiation, contract award, and then contract review. However, in a sales situation, you may simply have a catalog of products and services and a sales office taking orders over the telephone or over the counter. The contract review element of this operation takes a few seconds while you determine if you can supply the item requested. In an organization that produces products to specific customer requirements you may in fact carry out all the tasks in the contract acquisition process. Rather than isolate the contract review task and produce a procedure for this, your business may benefit more from a procedure or series of procedures that covers the contract acquisition process as a whole. 

As stated previously, traceability is fundamental to establishing and eliminating the root cause of nonconforming product and therefore it should be mandatory in view of the requirements for Corrective Action. Providing traceability can be an onerous task. Some applications require products to be traced back to the original ingot from which they were produced. In situations of safety or national security it is necessary to identify product in such a manner because if a product is used in a critical application and subsequently found defective, it may be necessary to track down all other products of the same batch and eliminate them before there is a disaster. It happens in product recall situations. It is also very important in the automobile and food industries in fact, any industry where human life may be at risk due to a defective product being in circulation. 

Case study 5 provides an example from the offshore oil and gas production industry, and illustrates the fact that in solving a specific practical problem, a practitioner will utilize a wide variety of formal and informal methods. Table 7.1, which describes some of the methods used in the study, includes several techniques discussed in Chapter 4, including interviews, critical incident techniques, walk-throughs and task analysis. 

About 2.5 million tons (2.3 million tonnes) of coal arc burned daily in U.S. power plants. This is equivalent to roughly 21,000 railcars in transit, so it is apparent that coorditiatiiig production and cotistimp-tioii is no easy task. Accidents, rail strikes, natural disasters (e.g., floods that take out bridges and rail lines) and severe weather (e.g., deep river freezes that halt barge traffic) can all severely disrupt deliveries for utility customers dependent on a reliable coal supply for base load plants. Nonetheless, to reduce costs U.S. utilities have significantly reduced typical inventory levels over time. Wliereas a coal inventory of ninety days of supply was once typical, inventories now frequently run in the range of thirty to forty-five days. 

The analysis of the Test of Gained Knowledge showed that the great majority of students (Task 1, f(%) =93.36%) was familiar with the definition of reactants and products and was also very successful in the recognition of reactants and products from the descriptions of simple everyday life processes or various wet laboratory... 

The plasma-catalyst system utilizes plasma to oxidize NO to NO2 which then reacts with a suitable reductant over a catalyst however, this plasma-assisted catalytic technology still comprises challenging tasks to resolve the formation of toxic by-products and the catalyst deactivation due to the deposition of organic products during the course of the reaction as well as to prepare cost effective and durable on-board plasma devices [47]. 

There are many products based on these life sciences standards, such as the aforementioned gene expression standard that is used in Rosetta Merck s Resolver product and the European Bioinformatics Institute s (EBI) Array-Express database. The LECIS (Laboratory Equipment Control Interface Specification) standard is used by Creon as part of their Q-DIS data standard support (note that one of the authors was the finalization task force chairperson for this standard). 

Below, the procedure for the determination of dominant campaigns in a version that was proposed by Lazaro et al. (1989) is outlined. Their methodology includes enumeration of feasible production sequences, selection of dominant production lines, task sequencing, and search for an optimum with constraints. All possible production variants are generated by an enumeration procedure that takes into account the possibility of available equipment working in parallel, initial and final task overlapping, and instability of intermediate products. Non-feasible sequences are eliminated so that only favourable candidates are subjected to full evaluation. Dominant production lines are selected by maximizing the criterion ... 

Nevertheless, we should admit the major conclusion of the study by Morrison [8] that the task of attaining selectivity of gas sensors while using catalysts differs from that to obtain selectivity in catalytic reaction as justified. During gas detection one should make use of selectivity of reactants and the stress is placed on the study of capability to accelerate or slow down reaction of above particles whereas catalysis requires a selectivity with respect to products obtained necessitating tiie studies and monitoring of all stages of the process. Therefore, the direct use of catalysts of known reactions does not ensure obtaining desired results. However, in the cases when side products and reaction products do not...
