1) Slush Casting

Old, none

New,better

Slush casts are made by pouring a liquid into negative molds and almost immediately pouring excess out, leaving a layer of zinc metal inside. Ordinary plaster casts are made by slush casting, and the technique was used for casting small pieces in zinc. Zinc slush casting are necessariy smakk because a single person had to manipulate the combined metal molds and molten metal.

2) Key performance indicator(KPI)

Key Performance Indicator (KPI)

Key performance indicator (KPI), is a number or value which can be compared against an internal target, or an external target ‘‘benchmarking’’ to give an indication of performance. That value can relate to data collected or calculated from any process or activity.

It was considered that the KPIs within the manufacturing strategy are cost, quality, flexibility and delivery, as well as inventory [3]. A part of a project survey was carried out to identify which performance indicators

companies use and which ones they characterise as important. The top five were: profitability, conformance to specifications, customer satisfaction, return on investment and materials/overhead cost.

(M.M. Ahmad, N. Dhafr, Robotics and Computer Integrated Manufacturing, pp. 171-172)

New,better

The basis for all process controlling is a process-oriented key performance indicator system that links the process perspective to the essential controlling aspects of the business. The key performance indicators must enable concusions to be drawn regarding the effectiveness of the processes(e.g. customer satisfaction) and their efficiency (e.g. processing time, delivery reliability, process quality and costs). In addition, a process-oriented key performance indicator system is configured so that it is possible to make statements about the actual course of the process.

3) Fixed repeating Schedule

(old)

 A fixed repeating schedule can be made responsive to fluctations in the work by treating it like a set of reservations to be confirmed.In timetable planning, they are confirmed by changing background colour on a spreadsheet cell. The communication of this information to the shop floor, howevermay require printing and distribution of hard copy. This can be avoided by using kanbans for confirmation.

(Lean Logistics, The nuts and bolts of delivering materials and goods, Michel Baudin, p.293)

(new/better)

Implement green stream/ red stream or fixed sequence, fxed volume to establish the entry and exit criteria for products from these streams and establish the supporting disciplines in the support services. The cycle established will produce Every Product Every Cycle (EPEC). This is a spesific form of Fixed repeating Schedule. Green stream products are those with predictable demand, Red stream products are high value unpredictable demand products.

4) Automated Conveyance Systems

Old-none

New, better

Automatic Conveyance Systems have been developed, which reduce labour and improve safety while transporting segments and materials from the warehouse to the cutting face.

The automatic conveyence system comprises automated stockyard and transport system, and a supervision cpntrol system. The stockyard makes use of advanced warehousing technology, and can move materials in and out of the warehouse automaticlally. Automates vehicles transport materials from the shaft to the vutting face. Control of the process is conducted through the use of optical fibre and wireless induction.

5) Nano electromechanic systems

Old-none

New, better

Nano electromechanical systems NEMS are investigated because of their promissing features regarding sensitive tools for sensor and communications technology. This systems may also be used as “quantum mechanical” resonators which allow to explore mechanics in the quantum mechanical range when operated at several GHz at ultra low temperatures. In the first part we want to address different detection schemes necessary to achieve sensitive displacement detection for NEMS. It is shown that the measured Q-value of this structures depends on the detection scheme used. This fact permits to increase the sensitivity of those systems by using the appropriate detection technique. In this way a handle on quantum squeezing experiments wtih these mesoscropic mechanical systems is attained.
