Planning in production systems Production schedule planning Slovak University of Technology Faculty of Material Science and Technology in Trnava

Production schedule planning Creation thick production schedule - production quantities, allowances and terms – following  going order - build-to-order by concrete customer  prognosis by future sale - in series, connection. Collective production Find out sales activity decision for single manufactured parties through the medium prognosis and deal their by month = attune their with existing production size and going warehousing supply

Insufficient production island capacities = fit into a schedule too product lines, that are guard best capacitive compensation of available source. Activities  Prognosis demand  Planning custom order  Rough terminal custom order  Orientation calculation capacity  Gross calculation consumption of material

Planning of material request Farming with material Arrangements needs for material safety production concerning of type products, quantities and termsvzor textu... Designation of quantities  manufacture spare parts in corporation  shopping part

Planning steps:  piece list management piece list - allows budget for every product, of which subgroup and accessories is consisted, what are sum total part of accessories necessary for finished piece  decomposition request primary terms decomposition secondarily terms (subgroup, parts) secondarily terms must have towards primary certain temporal armature free stroke  Identification production batch and order quantities cumulating quantities of individual part, that are it is necessary produce whether procure, in production order (form production batch and order purchase  following request last step of planning in material request

Result of planning material request  we know how, in which partial temporal period are made order customer's parts and when they have exist safety bought out parts. Activities characteristics  Material resource planning  Calculation size supply  Calculation order quantities  Order material

Term and capacity planning Exact designation time of operation individual part exit in production, determination of startup and definitive terms. Finding concrete capacitive of load individual production furnished following acquaintance time of operation and terms. Capacitive removal following acquaintance of capacitive load

For every operation it is necessary to know:  Time of preparing for production furnished  Time of realization  Propagation time to following operation  Calculation of continuous time of young and old order production (production batch)  Maybe to assign earliest and latest booked and definitive terms for production canvass, times production start near line  Realization of capacitive compensation parties of production resources.

Production planning Combination of planning algorithm  Appraisal and predictions  Deadline capacity planning  Workshop planning and optimalization production Exploitation of dynamic planning material, co- operation, worker or profession and implements Combination of model production on store or production by order Formation enter in production in form optimally production order and production allowances

Basic functions Evidence of production prohibition  direct drive on demand, store ready production, working out production  selection suitable production variants, recommendation of production allowances  calculation of term supplies Dynamic plan consumptions material  claim to issue in production  direct drive on exposure canvass and on supplied storage facilities  reservation of strategic material

Capacitive calendar  for workstation, shop floor, centre  single maintenance through the medium of formula hours  evidence season and no-working days  planning repairs of machine balance deadline planning  balances claim to capacities, material, parts and semi finished goods, worker tools, financial fastidiousness  exploitation for yearly, monthly till daily planes, from time to time deadline balance sheet work

deadline planning  tool for businessman and controller of production  confirmation of term canvass, occupation of capacities standard place of work  exploitation of theory narrow spoil at production  solution of technological sequence production batch, included limited factor – machine x tool workshop planning  interactive creation front claim to workstation  in detail workshop planning inclusive optimizing algorithm  control production balances by quantities on buffer store

customer planning and production management  planning of individual prohibition  job-order manufacture or evidence prohibition - production order and batch internal production order  possibility assign optimally production batch for production on store  during production reserve quantities for incoming offer planning co-operation  work with alternative production in business or form co-operation  chance to follow alternative course of production

General map production infrastructure following entire portfolios claim to production ↔ draft plan of course production ↔ control of disposition source ↔ consequential calculation of suitable progress possibility of variant solution of the chief progress - alternatively production roads, substitute material or co-operation modification of plan ( obligation cut-down from time to time, date of delivery, minimize of supply) - by increasing the capacity or parallel operation over more technology

Material request planning scoring of availability shopping material in real time material can able to influence planning algorithms or is provision subsequently method JIT (Just in time) internal evaluation of purchase by setting criterion – admonish service on obligation order material, elect substitute supplier, substitute material – so called critical uncollected items

Planning the production process in-definition tree structure of technology manufactural process stream modeling from delivery of material in plant after finished product designation priority, criterion, given technology binding on consumer and supplier and commercial style companies for formation of optimally plan, possibility reservations material, semi-finished product from time to time following and scoring offer and load everyone's production resources

Optimalization of production process gadgetry for update data from production right on the planning screen ↓ following filling production on operational levels correcting of operative in due course production without obligation corrections plan, possibility to re-plan production
