Chain Problem

Metal stampings are an important manufactured product. Their production cycle includes the steps of part design, process and tooling design, tooling construction, and production. Each of these activities may be performed within departments of a single manufacturing plant, but more commonly are separated across firms and are widely distributed geographically. To be most effective, this process should be performed concurrently, with considerable flows of information along the supply chain. Research on Agent-based systems shows they are very promising in this type of task as individual agents can wrap particular domain knowledge and analysis algorithms, are always available to respond and are able to autonomously form networks as needed to complete product and process design tasks. In this paper we examine the particular case where alternate suppliers may be selected to supply components to the supply chain. Agents are used to connect the suppliers to the supply chain network. Each supplier firm’s agent understands the firm’s production capabilities, costs and capacity loading, and is able to negotiate with a broker agent representing the stamped part customer. A prototype system is described, and case studies are used to show the benefits of an Agent-based approach to this supply chain problem.

This paper presents a methodology for the simultaneous product and process design of components manufactured in small and medium lot-sizes. A key aspect of this methodology is to ensure that such components are manufacturable for the lowest possible cost in specially designed manufacturing facilities such as manufacturing cells. A computer-based design environment is proposed to cooperatively assist product designers in performing this task. The design environment is based on the model-based reasoning concept. Explicit product and manufacturing facility models are presented to support the reasoning process. These models are based on a combination of feature-based, geometric and process performance models. The reasoning mechanism is based on the Multiple Cooperative Knowledge Sources (MCKS) paradigm with explicit separation of domain and control knowledge. Domain knowledge sources deal with the product and process refinement activities while control knowledge sources deal with managing the concurrency between these two activities. The framework of the design environment is described in detail and justifications are provided for the modeling and reasoning mechanisms chosen. Preliminary results obtained from an implementation of the design environment for the simultaneous product and process design of Bearing Cages are presented. The paper concludes by summarizing the main contributions of this research and presents directions for future research work.

High world sugar prices: is Asia’s production cycle to blame?

High World

The current high world sugar prices reflect a major imbalance between global supply and demand, which has reduced stocks to very low levels. Although it remains to be seen whether prices will rise much above current values, it is clear that the supply chain will remain stretched throughout 2010 and this will help to maintain prices at a high level.

Chain Problem

Counterfeiting is a problem many companies do not want to acknowledge or talk about. However, ignoring the problem is likely to have the effect of encouraging counterfeiters to go unchecked. A multilayered strategy that adopts several approaches and engages the entire organization is needed to address the counterfeiting problem. This chapter provides a set of recommendations to address the issue of counterfeiting. Initially, the size of the problem must be estimated and the return on investment approximated. This can help define the need for a team of experts to work in this area, leading to a set of performance metrics that are aligned with business objectives and outcomes. Next, the key focal product segments should be targeted and a system for identifying products through product trademark registration with customs authorities should be completed. In the end, combating counterfeiting is not a supply chain problem, it is not a legal problem, nor is it a packaging and covert marking problem. It is a global problem—one that impacts all organizations, large and small. All business functions need to be part of the discussion, not just a single brand security function. Failure to approach counterfeiting in this manner will simply allow the problem to continue to grow.

The Impact

In pharmaceutical manufacturing, the utmost aim is reliably producing high quality products. Simulation approaches allow virtual experiments of processes in the planning phase and the implementation of digital twins in operation. The industrial processing of active pharmaceutical ingredients (APIs) into tablets requires the combination of discrete and continuous sub-processes with complex interdependencies regarding the material structures and characteristics. The API and excipients are mixed, granulated if required, and subsequently tableted. Thereby, the structure as well as the properties of the intermediate and final product are influenced by the raw materials, the parametrized processes and environmental conditions, which are subject to certain fluctuations. In this study, for the first time, an agent-based simulation model is presented, which enables the prediction, tracking, and tracing of resulting structures and properties of the intermediates of an industrial tableting process. Therefore, the methodology for the identification and development of product and process agents in an agent-based simulation is shown. Implemented physical models describe the impact of process parameters on material structures. The tablet production with a pilot scale rotary press is experimentally characterized to provide calibration and validation data. Finally, the simulation results, predicting the final structures, are compared to the experimental data.
