Chain Case Studies

While companies talk about networks, the creation of demand, supply, and innovation networks requires focus, time, and effort over many years. Here we share case studies of three companies that drove success and follow with examples where failure in the network created market turbulence.

To illustrate its application, we return to our supply chain case study. In Section 28.5.1 and Figure 28.7, we see that the longest lead-time operation in the supply chain is 45 days at Old Line, one of the suppliers...

Not aii moiecuies are suited for estabiishing SAMs. The majority of cases studied have invoived assembiy of aikyi-chain-based entities. The moiecuies of seif-organizing chemicai compounds aii have a simiiar stmcture. The spontaneous nature of fiim fonnation is due to the interaction energies of the monoiayers. These can be considered in tenns of tiiree main components (figure C2.4.i0) [121], which cooperativeiy estabiish stabiiity, order and orientation in the monoiayer. 

The first case study shows how a knowledge of steel microstructures can help us trace the chain of events that led to a damaging engineering failure. 

However, in the case of a root cause analysis system, a much more comprehensive evaluation of the structure of the accident is required. This is necessary to unravel the often complex chain of events and contributing causes that led to the accident occurring. A number of techniques are available to describe complex accidents. Some of these, such as STEP (Sequential Timed Event Plotting) involve the use of charting methods to track the ways in which process and human events combine to give rise to accidents. CCPS (1992d) describes many of these techniques. A case study involving a hydrocarbon leak is used to illustrate the STEP technique in Chapter 7 of this book. The STEP method and related techniques will be described in Section 6.8.3. 

We shall consider now the various degrees of order which characterize polymeric molecules. The addition of a monomeric unit to a growing chain may take place in more than one way. In the case of a vinyl or vinylidine monomer, i.e., CH2—CHA or CH2—CAB, head-to-head or head-to-tail addition may occur. In most cases the head-to-tail addition has a vastly greater probability than the head-to-head or tail-to-tail addition, and thus the latter is responsible only for small imperfections in the chain structure. Studies of head-to-tail and head-to-head additions were vigorously pursued in the 30 s and 40 s, and a good account of this work is available, for example, in Flory s recent monograph.15...

In the given case study, it is possible to introduce additional terms into this comparison which may look at energy implications such as process machinery and infrastructure life cycle energy costs, warranty repair, supply chain PSS, for example, depending on the company s scope and business model. 

Abstract Life cycle assessment (LCA) is a useful tool to assess impacts of cradle-to-grave chains of products/services. In the Riskcycle framework, the focus is on additives. Additives are usually minor constituents of products, but depending on their specific properties they can be important in the total scope of impacts of such products. In the LCA literature, additives are hardly visible. Most case studies of products containing additives do not mention them. The reasons for this are unclear, but are at least partly due to the fact that information on additives is not included in standard LCA databases. This is true for both life cycle inventory (LCI) and life cycle impact assessment (LCIA) databases. Therefore, it is difficult to conclude whether or not additives indeed are important contributors to environmental impacts over the life cycle. 

So from the point of view of additives, it seems that they may indeed contribute significantly to life cycle impacts. The case study of PVC flooring shows that additives contribute significantly, not just to toxicity impact due to DEHP emissions but also to global warming due to GHG emissions along the Cradle-to-Grave chain of the compound DEHP.

As sketched out initially, simulation can be used at different points in time of a production system lifecycle and with a different scope (see Figure 2.1). Considering the lifecycle and the scope, the three case studies described in this section may be classified differently, from supply chain to plant level and from planning to daily operation.
