Qusetion-2 The eight important questions given below for the future state design are to be answered. Q1.Elaborate the concept of Takt time? Assuming the monthly average, 20 working days taken by the FEI Company, comes to 5 working days per week, wherein everyday there are two shifts of 8 hours, and each of the shifts has two breaks of 15 minutes which ultimately can result in the time of production, availability of 7 hours and 30 minutes in each shift. Available Production Time = 7.5 Hours/shift The production time that can be accessed can be converted from hours to seconds by multiplying with 3600 Available Production Time = 7.5 (hours/shift) * 3600 (seconds) = 27000 seconds/shift. For calculating the daily available time, available production time has to be multiplied with number of shifts which is 2, Available Production Time= 27000 seconds/shift *2 = 54000 seconds/day. 24000 per month hydraulic control sections are needed by the customer. In order to quantify the customerโs regular needs for hydraulic control divisions, it has to be divided by the number of Companyโs working days which is 20.

Daily Production = 24000/20 = 1200 piece per day. To derive the Takt Time in the Farm Equipment Company, it has to be calculated like: dividing the Available production time by the daily customer demand as exhibited below: Takt Time = the daily Available production time/ the daily customer demand Takt Time = 5400/1200 = 45 seconds. The illustrations shows that the Farm is required to generate the hydraulic control divisions in each 45 seconds to fulfill the customer needs in the given hours availability. Q2.Does the specified company utilises finished goods supermarket or should it opt for the shipping system option I.E. FIFO? The Farm International, which delivers the hydraulic control section, are available in the 30 various lengths, 3 different diameters, and 2 several kinds of connectors. At the end of every hydraulic control section, there may be a unique connector. The Company is approximately supplying 360 various finished hydraulic control sections and due to these many vast availability of the variety, it is tough to develop more than 360 complete goods supermarkets. The Company avails direct shipping for the implementation of these sections, as it helps in reducing both the inventory levels and the money associated to this inventory. Q3.Where can the company initiate the continuous flow? The time data cycle, when figured out, results from the aforementioned two processes of cutting and matching takes shorter time as compared to the Takt time even while their rotational time is different and impossible for flow rationally and continuously. Whereas the other three processes, welding 1, welding 2 and deflash, possesses similar cycle being in the similar process family.
Combined together, concrete time for individual process is 40 seconds while the operatorโs cycle time is 10 seconds and its 30 seconds for the machine. The all combined cycle time is lower in comparison to the Takt time and also proved that the rationale and non-disturbed flow is possible amongst the above mentioned three processes. Figure 2:The current time scale factor Abovementioned diagram shows that there is 195 seconds cycle time in the given assembly which is far higher than the Takt Time of 45 seconds. The complete assembly work content when divided by the Takt Time results in the number of operators required to run assembly at takt. Number of Operators Required = Total Cycle Time / Takt Time = 195/45 = 4.33 Operators
When logically thought, will the five operators be selected, bring in the content of the work within the Takt Time? Currently, real time workstation is managing with 6 operators and the cycle time taken is 195 seconds. But, a Kaizen has to be applied to the workstation in order to optimize the process and also eliminating waste. Kaizen is also applied to lead the cycle time within the Takt time. Considering 5 operators, the fresh cycle time taken for the workstation should be derived by dividing cycle time with the number of operators. The cycle time of assembly workstation = Total cycle / Number of Operators = 195/5 = 39 seconds. The cycle time of the assembly workstations is 39 seconds with 5 operators, with a difference of 6 seconds in the Takt time. Q4.State that the usage of supermarket pull systems by the Company? The Company can build its first supermarket pull system on the front side of the machining and cutting process considering that the raw goods provided is coming from the two different suppliers engaged it the Company. These suppliers are Kentish Tube System Ltd providing tubes and Essex Casting Ltd engaged in the supply of raw castings for the end connectors. The system of the pull belonging to the 2ndsupermarket has been amongst the cutting workstation and the welding1, welding 2 and deflash workstations, together along with the machining of casting workstation and the combined workstation. Such application is done in case of the various running cycle times amongst these processes. Summarizing, the cutting and

machining cycle time is much rapid as compared to the combined workstation and the Takt Time. The Company also works to cling a production Kanban to each of the 5 available hydraulic controls in the supermarket, and also utilize the same to acknowledge the cutting and machining process in cases where bin has been eliminated from the supermarket, which shall also enable the instruction of cutting and machining to produce the 5 spare parts and move the same to the supermarket. Q5. In the production chain, which is the single point that the company must schedule? The Farm International Company has specified the scheduling point, being concrete workstation welding 1, welding 2 and the deflash. This stated central area shall monitor the Companyโs whole steering- bracket value stream, by hiring the First in First Out method (FIFO). The products must also be sent to the painting, also the assembly workstation and finally to the shipping unit. Because of the downstream of the pacemaker processes, the steps should be carried out in an order. Kanban would be sending orders to these workstations for the production to start in the processes of cutting and machining. Q6. In the pacemaker process, what should company do to adopt the production mix? At the pacemaker processes, balancing the production mix requires Company to apply a Heijunka box which if created by the Kanban slots, is utilized as leveling load box for every single product configuration. Every Kanban card is inclusive of the 5 hydraulic control sections.
Considering these sections, it will benefit in estimating the both the quantum of work and time for its production. Q7. For maintaining consistency in the pacemaker process, which consistent work process must be released by the company? The consistent work increment of welding1, welding 2 and deflash workstation will be arrived at by multiplying the 45 Takt time with 5 pieces per tray pack size. Work Increment = Takt Time * Pack Size = 45*5 = 225 seconds = 3.75 minutes. Illustrations shown above are done to show calculations regarding the hydraulic control section pitch, and the consideration amongst one Kanban for single tray of 5 hydraulic control sections. By showing this calculation, it is implied that the Company would attempt on the work instructions, one Kanban at a time and scheduled withdrawal of finished goods at its welding 1, welding 2 and deflash workstation. As shown above, in the time gap of every 3.75 minutes, the material handler would invite the next Kanban to the welding 1, welding 2 and deflash workstation and also roll back the empty trays in the finished goods area for filling. Q8.Enumerate the improvement processes important for carrying out the value stream of the company to maintain as the future-state design suggests? To facilitate improvement in the Company processes, it is always better to have a value streamline. Below are the process improvements highlights which must be implemented and executed:
โฎFor effecting reduction in the lead time of production, the painting contractor must always be inside the factory. โฎThe operators currently working in the assembly station must need reduction to five operators and made to work at a stretch in a flow. โฎSupply should be doubled instead of once in every 14 days. โฎFor reducing the lead time under Takt, a combined workstation of welding 1, welding 2 and deflash must be developed. โฎChangeover time must be reduced in the cutting and machining of casting workstation. โฎBy reducing and if possible, extinguishing all the waste, the rotation time taken by the assembly workstation must be reduced from 195 second to 39 seconds.

Question-3. What is future state map for specifying important processes for operating factory as per the lean manufacturing principles. Value Stream Mapping is required for operating the lean manufacturing process. VSM is nothing but mapping of available material and the information flows which are needed to synchronize amongst the tasks which are carried out by the manufacturers, suppliers and the distributors to deliver the products to its customers.
Question-4 Show light on the execution plan for the Farm International to switch between present state to future state. The points given show the implementation plan of the Company to change from present to future-state Changing from the current state to the future state the Company requires implementing the lean manufacturing. To have a successful implementation the company should follow the below. Farm Equipment Company, in order to shift from current state to future state, must execute the lean manufacturing, for which steps are given below: Future State Scope must be observed and identified so as to formulate the first implementation project along with the long term specs. Creating short term plan is the foremost step, in order to execute the future state gradually during the first year. A detailed plan should work and will facilitate Company for using the available resources to optimizing the current state. This is done basically to build a long term implementation work for application at each step for consecutive 3-4 years. This execution of the future state will give rise to the new issues which must be resolved and there will be different changes in the future map but always trying to keep the leadership focused on Lean for long term. 1.Future State to be introduced into the Company... The second is introducing the future state within the company. Simplify the ideas for itโs the employees with the help of diagrams, posters and signs. Imparting standard training schedules for all the employees engaged in future state project is highly recommended. Such courses will include the changes track and the reason of carrying out such changes. This knowledge shall also help learning the lean manufacturing processes. 2.Communication and feedback channels must be created within the Company.
In this step, the Company has to focus at involving everybody and inviting to take part in the upcoming projects. This is done to get the extended support of the people at large and spreading new positive vibes for building strength for proper lean manufacturing journey. 3.Revitalizing existing agreements and building new agreements. Reinforcing existing bonds and building new ones according to the new specifications. For creating new agreements, the lead time must also be reduced from 16 weeks to 8 weeks and the delivery time or supplies must also be lathered. 4.Building new Floor Plan A new floor layout is required for enhanced working with modern tools. The workstations must be situated closer to each other and should also be re-organized for a better work environment. 5.Performance Tracking and making the results viable. The Company has to ensure that the data is contently checked and regularly inspected. 6.Selection of skilled professionals to increase production Highly skilled set of professionals must be hired to impart proper training in the lean manufacturing and also to technically advise the managers. Field master must also be appointed to deliver quick and better results. BIBLIOGRAPHY:
