The productivity improvement means of the handwork line

　The index which shows the productivity of the construction the main constituent of which was a handwork, the manufacture line (the line of the Man neck process) has [the yield in 1 man-hour].
It put the productivity of this handwork line below about the aim and the improvement technique of the improving improvement in order.

The aim of the productivity improvement

1) The abridgment of the production cycle time
　The improvement which reduces a production cycle time with the work personnel being constant because it doesn't produce in overwork and holiday mobilization in case of expansion of the production request quantity
2) The work cutbacks in personnel
　The improvement which does a work cutbacks in personnel without changing a production cycle time (the request cycle time) when the production request quantity is constant
It makes above aim clear and it grapples by the following improvement procedure.

The procedure and the improvement means of the line improvement

The procedure	The improvement content explanation	The improvement The means example
1 step	･ It does the work pace investigation of 1 hour and it is the improvement of the loose factor of the work baton and improvement by the work overhaul. 　It exposes the improvement item of the loose (delayed) factor of the work baton from the result of the pace investigation. Moreover, it resolves into [the work overhaul worksheet](clicking this place) (the right hand, the left hand operation) for the element to work every element work. Then, it classifies each element operation into "the low additional value work" (the leaving, the movement, the carriage, the watching, the correction, the hand wait). It exposes an improvement item in the viewpoint of "the motion economy 4 general rule" (easy in the operation number decrease, the simultaneous operation, the operation distance abridgment, the operation) in them	・ The standardization of the work procedure ・The improvement of the low additional value work ・One taking, one piece of transference making improvement ・The automatic taking-out improvement of the product ・Correction's, adjustment's factor improvement ・The improvement of the way of the inspection measurement ・ It improves facility minor key breakdown individually. ・The one touch making improvement of the part supply forwarding container on replacement
２ステップ	・The improvement of the loose factor of the yield for every the time Next, it grasps the present situation in the loss which occurs in the work in every day. The way of grasping the present situation records "the yield for every the time" for 1 week and makes the looseness of the yield for every the time a histogram. (When recording a yield for every this time, for the 1st hour of the morning, in plan exchange, in case of the facility trouble, it records to understand time of part's being broken, and so on.)	･ The improvement of the work preparation abridgment of the morning ・ The improvement of the management record work ・The individual improvement of the plan abridgment ・The improvement of the production lot size ・The facility trouble analysis and the recurrence prevention ・The improvement of the way of the production indication with the pre-process ・The improvement of the way of the grasping for every the time of the production progress
３ステップ	・The improvement of the linear balance In above improvement of 1-2 steps, the linear balance rather collapses. The way of improving the following linear balance depends on the aim of the improvement here.The aim of the improvement is "1) the abridgment of the production cycle time" or "2) the work cutbacks in personnel". It shows the net time of each process in the linear balance table. 1) The aim of the production cycle time abridgment It moves the part of the work of the neck process to the process with the other low degree of the fullness. Or, it implements the element operation improvement of the neck process more. 2) It is the aim of the reduction in the work personnel. It moves the work of the process with the lowest degree of the fullness to the other process and it reduces the work personnel of this process. However, when the work personnel can not be reduced, it assembles in implementing similar improvement with the other line and then the fraction personnel. Then, it makes this relieving Man, we have lack man-day around and it makes production. (Making a line a big room) It had better implement the improvement of the laying-out of a process in the step which implements above improvement. When it is better not to implement the improvement of the laying-out in the step of step 1-2, the writer thinks.	･ The separation movement of the process of the work ･ The improvement of the way of the part supply forwarding ･ The improvement of the process laying-out ･ The combination with the other line and the collection (The arrangement of the standing in the row of the line)
４ステップ	・The improvement of the work organization combination to the change of the request production 　Next, the change of the request production becomes the adjustment of the load time in the fluctuation of the number. However, when request production is mainly changed, the fluctuation of the required personnel becomes necessary of course. It sets personnel arrangement and a routing in the combination not to make linear balance percentage decline to the change of the production. Moreover, it is construction in the process laying-out which is the optimal for the required personnel. It improves that it is possible to do a laying-out change more simply. By the production method. It produces at the cycle time which adjusted a line to the request quantity "The intermission production".It produces constant quantity in the gathering and it wanders a line "The visitor production".It examines well and it decides which above production method is efficient. Seemingly, "the visitor production" can be efficiently seen. However, it has made stock in quantities during the following process and moreover it causes the loss of the container and the carriage."Intermission production" As for the production, the efficiency of the facilities declines. However, to produce necessary quantity minutely, being raw, the stock during the following process is the least and finishes. In the production request quantity, as for the non-mass production, "the gathering visitor production", in above the quantity production should choose "the intermission production".Incidentally, make the production lot of the taking of "the gathering visitor production" the inside of the range with the production of the forwarding cycle.It begins at the 1 division production in the forwarding cycle and moreover it should improve for the 2 division production. When the facility trouble and so on generate the risk of the 1 division production while producing it, the product to produce is after that because it generates, forwarding back. The minimum forwarding becomes of the production above 2 division possible.	・The combination improvement by the request quantity change personnel ・The improvement of doing the laying-out change becoming of the easiness ・The setting of an optimum production method ・The improvement of the division production method to the forwarding cycle ・The combination with the other line and the collection (The arrangement of the standing in the row) ・The combination of the non-mass production line and the improvement of the generalizing
５ステップ	・he improvement of the flow and the way of the one with the back and forth process of carrying and the improvement of the production indication method 　It improves a state (the production lot size, the style of packing, SNP, the way of carrying, the carriage baton) of the flow of the flow of the one from the pre-process and the one to the rear process. It improves stock, arrangement lot stock, complete stock, carriage loss and so on during the process.	・The synchronization of the production cycle time ・ The unification of the container, SNP ・The improvement of the way of carrying ・ It improves to the linear direct connection of the back and forth process. ・ It improves for the management which can be seen by the eyes of the production indication, the forwarding indication.
