The manufacturing operation of the enterprise manages, the conformity of 5 great natural resources that is an enterprise rises, become very effective run a system. This 5 great natural resources are respectively: Manpower, equipment, stock, art of composition and information. And carry index of 6 bassoon manage, namely PQCDSM, can realize control production to run a system, let it can realize the conformity of afore-mentioned pair of 5 great natural resources, realize efficient manufacturing management thereby, improve manufacturing efficiency.

Discuss an enterprise to produce the stand or fall of management, centered at 2 o'clock commonly, namely the effect and efficiency. It is to should do right thing above all, what talk here is the effect, it is directional problem. Do a correct business namely, want way first the choice is right, just get wanted result possibly. It is correct ground works next, what talk here is efficiency, it is methodological problem. Use accurate method namely, had done a business, improve efficiency, with least investment, get yielding at most.
And can exist below actual manufacturing condition a lot of elements can bring about an enterprise to produce efficiency to be achieved hard 100% , and an enterprise is like machine equipment to quit movement, with respect to the fall that can cause an enterprise to manufacture efficiency. To all sorts of stopping engine loss undertakes summing up, can do following classification:
1, plan loss, planning what the loss points to is plan sex stop production, can stop engine loss with what anticipation arrives, this kind of loss is inevitable below a lot of circumstances. Deduct plan loss, the working hours that remain calls " bear time " .
2, time loss, this share loss is to point to outside removing plan sex stop production stop engine loss. If say plan loss is inevitable, so pass ameliorative management, time loss is OK however reductive. Deduct time loss, remain " bear time " call " sow uses time " . Specific and character, time loss is OK reduce: Misgovern, switch on the mobile phone maintenance of switch of preparation, product, breakdown.
3, performance loss, because lack maintains,what performance loss points to is, machine cannot full load production, perhaps need brief halt plane. Deduct the time with performance wasteful loss, remain " sow uses time " call " clean sow uses time " . Specific and character, property damage owner of lost property wants to include: Loss of brief halt machine, speed.
4, undesirable loss, because manufacturing product is unqualified,what undesirable loss points to is, cause the loss that produces afresh. Deduct the time with undesirable wasteful loss, remain " clean sow uses time " call " valuable time " . Specific and character, undesirable caustic owner of lost property wants to include: Make nap of undesirable, do poorly done work over again.

What the 9 big losses that produce efficiency as a whole point to is a plan loss of machine of maintenance of switch of preparation of sexual stop production, misgovern, start working, product, breakdown, brief halt, speed, make nap of undesirable, do poorly done work over again. Be aimed at these losses, the method is improved in what correspondence exists in seed profit management.
One, loss of plan sex stop production improves strategy
1, aggrandizement information obtains capability, borrow by EDI (electronic data exchanges a system) with POS system, give manufacturing branch make known to lower levels a smooth order, can avoid so unused because of the wave motion of order more equipment.
2, foster and use can be versed in more, when demand is off-season, can foster can be versed in more, although the person is a few less, also can finish manufacturing job euqally. In busy season when, send a company to cooperate each other with the talent, collocation uses casual.
3, other method, besides, still have a lot of methods, be like: The lot that reduces order to order, shorten the manufacturing cycle time of the product, all product does not organize sales promotion activity, with the anticipation of business of avoid sale channel to the price.
2, start working prepares / improvement of product switch loss is politic
1, value shedding analyses a way, the company whole value flow has an analysis, controller should observe how needless movement is formed, whether to need to do, after unlock restricts a condition, these needless worthless movements can be liberated to come out.
2, after undertaking to company flow value is analysed, should define a goal. After eye demarcate comes down, controller should think to undertake ameliorative according to 4 measure:
(1) delete, delete rubbish flow, eliminate to await thoroughly, search, carry, the examination move that does not produce value.
(2) amalgamative, handle dispersive movement centrally, group of groups of JIT change can be versed in more also is a kind of skill is exercise, amalgamative.
(3) recombine, the order that works around arranges combination afresh, for example: Change a pattern quickly / the principle that changes a line.
(4) simplify, make a thing simpler, better do, for example: Prevent slow-witted gimmick, tool to treat those who provide apply.
3, equipment malfunction and function reduce a loss to improve strategy
1, all sorts of equipment malfunction stop machine losing to improve strategy, TPM gives 5 kinds of reasons to the problem summary of equipment occurrence malfunction, also put forward 5 kinds to resolve the way to deal with a situation to this at the same time:
(1) the reorganize and outfit of postulate is the 3 big postulate that pressing with a finger maintains independently to equipment, sweep namely, originally again closely to oil and bolt, establish an operation fiducial and hand-in-hand travel grooms, this is called in abundant field company " defend slow-witted measure " .
(2) what the abidance of use condition points to is, want the measure that method allows employee to abide by a company to make. Should groom namely, should supervise, should assess, want to track, make sure employee executes an operation according to operation condition.
(3) deterioration recovers from an illness spread out those who point to is to drafting suitable regulation, below the premise that makes sure employee can be abided by, find appropriate method to recover from an illness the deterioration of equipment, recover from an illness with respect to what call deterioration.
(4) of weakness countermeasure carrying out is to be aimed at equipment to design what the weakness on undertakes to rectify and reform countermeasure. Its key is in how to be transformed afresh at product and equipment.
(5) of factitious error prevent, dot and correlation of this the a bitth photograph, apply namely prevent slow-witted gimmick to reduce the difficulty that carry out, undertake grooming accordingly, in order to had avoided much factitious error.
2, all sorts of function reduce efficiency losing to improve strategy, reduce the efficiency loss that causes to reduce equipment performance, need undertakes maintaining to whole equipment, basic reduce 5S, arrange namely, rectify, sweep, cleanness and discipline. The loss that equipment malfunction and function reduce, its improve strategy to return duty maintain at equipment. Basis 5S, equipment maintains the method of method and TPM, can solve efficiency losing problem well.

4, loss of rate of the equilibrium that make Cheng improves strategy
The key that leads improvement evenly is to break bottleneck, what improve whole flow in manufacturing system interior is lopsided. The key that unearths bottleneck is, no matter be production flow, still manage flow, let their vitrification, visible, standardization, stable change, such gift are only nice management.
1, of bottleneck search a method
(1) observation law, namely controller examines each working procedure in the workshop and each equipment, there are a lot of semi-manufactured goodses that need treatment before visit which working procedure or facility, probable this working procedure or equipment are bottleneck.
(2) do 5S first, through doing 5S first, make the spot sleek, namely the thing that the spot appears, as far as possible ration is restricted, this kind of method compares have the aid of to discover bottleneck easily.
(3) of IE apply, have the operation on paper through IE, computation the basic cycle time of each working procedure, according to academic time calculate, will reckon bottleneck is likely is which labour.
2, the settlement of bottleneck method: Make full use of all time in bottleneck; Do not let bottleneck has any waiting for to expect and produce shutdown loss; Do not let bottleneck produce brief halt engine, perhaps produce speed to reduce; The movement that does not allow bottleneck existence the slightest amount or degree is wasted and process waste; Do not make bottleneck generation undesirable taste; Of working procedure of the line after reducing bottleneck undesirable or discard as useless, in order to reduce the chance that bottleneck increases production again; By bottleneck forward line working procedure passes demand information; Acquire equipment, in order to exclude the bottleneck effect to whole production efficiency.
3, the method that solves a balance to lead an issue: Let automation line vitrification discovers easily with creation and solve the condition that balances a problem; Move the job of the height to trough to do; The personnel of trough supports the staff of the height, alleviate the workload of height post; Change definitely through making the same score think method to change amount and breed on average.
5, make undesirable article with make overmuch efficiency loss improve strategy
1, build efficiency loss to analyse a mechanism. The premise that the mechanism builds is the environment that innovation gives to let problem float easily come out now and condition, the streamline that innovation goes to discover the environment of the problem and tool use operation for instance easily is changed, behavioral standardization, spot is visual change, An Deng management.
2, measure to analyse project set fiducial. Undertake efficiency losing is analysed, what should measure to analyse project set is fiducial. Object check and correcting an error with too complex method namely, want to use the the simplest, most accurate method to solve a problem, because complex itself is a kind of waste.
3, build data to collect flow and authority duty division of labor. Relevant administrator must reach the spot in the time in the regulation, solve a problem according to actual condition. Abbreviation of this kind of method " 3 now " : Show the ground namely, show content, reality. Through limitting the power of draft resolution system, QCC and QIT duty differentiate, unite the method that solves a problem and tool, encourage everybody to use the collective improvement after uniting language.
4, the feedback that builds analytic result / report a system. Through building the mechanism that lets problem float easily come out now and environment, discover through the spot and solve a problem, reach rectify and reform information correctly, feedback headstream branch, take out to rectify and reform a file by headstream branch next, carry out go down, happen in order to avoid same mistake again.
Through discovering a problem ceaselessly, solve the problem, feedback that builds analytic result / report system, form a company of optimal practice experience accumulate platform, eliminate thereby undesirable tasted generation, realize reasonable production.
