3. © C.Hicks, University of Newcastle HICKS/3 Capital Goods Companies: Generic Issues Products are highly customised and are produced on a make, or engineer to order basis. Production facilities include jobbing, batch, flow and assembly systems as well as construction. Lead time reduction increasingly important. International competition: effective and efficient use of resources is very important. Complex and dynamic supply chains. Product offering broadening to include service elements. Involves civil, mechanical and electrical engineering.

8. © C.Hicks, University of Newcastle HICKS/8 Key Features Large scale model allows whole manufacturing facilities to be represented. Models facilities, products, processes, layout and planning and control systems. Many product families can be represented with shallow, medium or deep product structure. Hierarchical description of products and resources. Allows variety of planning and control methods to meet local requirements. Integrated with scheduling and layout optimisation tools. Comprehensive stochastic modelling.

14. © C.Hicks, University of Newcastle HICKS/14 Stochastic Planning Methods Developed methods that either meet a service target or minimise the combination of earliness and tardiness costs. Investigated approaches for infinite capacity, finite capacity and dynamic scheduling cases. Planning methods investigated and validated through simulation modelling.

23. © C.Hicks, University of Newcastle HICKS/23 Supply Chain Management Modelled business processes using SSADM Company structures range from vertically integrated to project integrators that outsource all manufacturing. Important factors include: available capital, risk, potential utilisation of plant, capabilities, flexibility. Three stages of interaction with customers: marketing, tendering and contract execution “Normal” / “radical” design Functional vs. technical specifications Procurement decisions made by: customers, designers, procurement departments

24. © C.Hicks, University of Newcastle HICKS/24 Summary of contributions Planning, control and layout problems in capital goods companies. Outcome: first large-scale simulation model of manufacturing in capital goods companies Scheduling complex products in deterministic and stochastic environments. Developed first optimisation techniques. Layout analysis and optimisation. Developed integrated tool. Supply chain management in capital goods companies. New models proposed and linked to strategic issues.

47. © C.Hicks, University of Newcastle HICKS/47 SCM (continued) Majority of controllable cost committed at the design stage. Normal / Radical design Established / ad-hoc business processes Product offering broadening – shift from just hardware to retrofit, service and operations. There are high levels of uncertainty and sparse knowledge, particularly at the tendering stage. Tendering is often subject to severe time pressure and resource constraints.

The design, construction, and operation of the plants are different leading to different consequences in terms of capital and operating costs, quality, etc. The research aims to establish the relationship between capital cost, construction lead-time and operating costs and performance.
