PRODUCTION LOGISTICS Introduction Slovak University of Technology Faculty of Material Science and Technology in Trnava

Logistics Definition Logistics – logos = world, language - logistikon = intellect, resource Logistics is a science discipline about planning, management and control of material flows, people, energies, information about systems [Junemann].

Logistics Definition Logistics is organizing, planning, management and power goods flow. It starts by development and purchasing and finishes by production and distribution by customer order for fulfilment all market requests to reach minimal costs and capital payments. [European Logistics Association].

Logistics Definition Logistics is integrated planning, formulization, execution and checking of material and information flows from supplier to business, inside of business and out of business to customer [Schulte].

Logistics Definition Logistics is dealing with system solution, planning, synchronization, realizing and coordination of materials flows chains, information flows and financial flows from supplier to business, inside of business and out of business to customer. It is orienting to customers requirements satisfaction as an final effect. It tries to reach by the most flexibility, exactness and efficiency [Červeňan].

Production Logistics Production Logistics – summary of logistics tasks and licences for setting up and execution of production process. It contains all activities related to materials and information flow of raw, subsidiary and production materials from stock to production, from particulars steps of production process including all buffer stocks, assemblage and stock of finished products.

Production Logistics

Production System Projection = is a layout of positions carrying out production process in design area. There is needed to ensure continuous movement of raw and materials. The main factors defining basis of production system projection are: product, production facilities, volume of production, labour, statutory provision, buildings and lands.

Production System Projection Production programme is setting by: customer requirements, estimating sales development (Demand forecast) mixed technique. Production programme contains these parameters: qualitative (product type), qualitative (amount of products), temporal (delivery date).

Production System Projection Production facilities need The aim is to find out the need of production machine and facilities for allocating of functional sectors and buildings, for production devises layout. Detection machine and facilities capacity needs: 1. Range of produced goods analysis, 2. Setting the production run and performance standard of machines, facilities and hand workstations, 3. Determination the duration of workstation loading = number of produced components * planning time of workstation occupation 4. Required terms accumulation of occupation by all orders = TOTAL NEEDS TO PARTICULAR TYPES OF PRODUCTION FACILITIES FOR FOLLOWING PERIOD (the reserve – elimination spare machines or facilities, the absence – spreading machine stock).

Production System Projection Setting the labor need by qualification and profession for: major production, general and operate workers, operators for transport, handling, storage and packing, others additional activities.

Production System Projection The area need goes out calculated production machine and facilities need. The total area need consists of: areas for installation production machines and facilities, including additional areas, stock areas, transport and handling areas, social and administrational areas related by production.

Production System Projection Transport organization – goes out of planning production capacity. It uses a data from piece list and job description. Determined qualitative relations can be ordered to matrix chart or input output chart. The graphic presentation is Sankey diagram. There are marked particular units and production facilities by their layout. Then there are figuring material flows using different intensive join by their intensity.

Production System Projection 2 basic ways of laying out working positions: Technological – machines and facilities are grouped together by their technological relations (smithy, lathe positions). There is suitable to use is for often changes of production programme for solving problems of machine faults, stocks defects etc. The disadvantage are hard traffic, long continuous production terms. Utilization: piece and small-lot production with various production process.

Production System Projection Objective – the positions are laying out by sequence of technological process operations. There are situated all working stations necessary for component, assembly groups or products production in one production unit. It is removing the disadvantages of technological approach. Its disadvantages is inelasticity against production programme changes, position failures sensitivity and creation deformities.

Production System Projection The next ones are: Nested – it is a combination of technological and objective layout. There are objective setting up groups called the nest in dominant technological layout. Stationary – the products are remaining on one place. The only one moving are workers (utilization: large product – ships, tractors). It is also called modular production. Individual – the positions are random laying out without evident relations.

Production System Projection There are some methods of laying out the positions: Method of the centre, Triangle method, Circle method, CRAFT Method, Coordinate one.

Production Management Production planning, Operative production management. Production planning is determining what will be produced, in which quality and when it will be produced, that is, the starting and finishing point and general production process running. Then it is defining the sources, i. e. setting the production factors consumption and finally where the particular product will be made, on which place and by whose worker. This concept involves activities hierarchy, starting by production programme creation through major production plan, term and capacity planning and production scheduling.

Production Management Operative production management – it is order setting to production, that is transfer production order and all inherent documentation and management of order process.

Production Management Operative production management tasks: 1. primary need estimating (amount of final products, spare parts including market requirements), 2. defining the secondary and third needs (consumption of raw materials, raw products, configurations and parts), 3. Designation the temporal development of need, setting the amount of safety stocks, 4. Defining the need guarding with own or external sources, 5. Estimating the largeness of production orders, 6. Designation the terms of production orders, 7. Timing the proper production run, 8. Securing plan execution, 9. Updating the background of operative production management by accepted changes.
