Thesis production planning

In addition, these planning approaches can extend the available production capacity, resulting in higher costs.

For the order interval, we suggest a 4-week period. In addition the Key Performance Indexes found in the MTO industry will be used as a base mark for PPC performance given the various manufacturing environments described. Design: A literature review will be conducted, identifying key literature that holds validity, both in terms of PPC methods and MTO environmental characteristics. In order to allow processing, generally two cards are needed, one for the loop of the previous and current station, and one for the loop of the current and next station. At the moment this barely done, while WLC is quite sensitive for incorrect processing times. New orders are released on a daily basis and when a station starving, i. The production plan is used by the production planner to construct the production schedule. The Simulated Annealing SA algorithm optimizes the initial production plan to lower the total costs. For this process, a lead time of two weeks is used in planning. The first method is Workload Control WLC , in which each station has a limit for the amount of work that is on the shop floor for that specific station. These IPPS approaches take product families into account, which make the approaches willing to combine soft drinks of the same product family in the same production week. First, the MTO environment needs to be defined.

Engineering and reengineering becomes part of the environmental factors complexity and dynamism that impact the applicability of a PPC method.

This production planning approach does not use the internally available inventory capacity as a restriction, making this planning approach not account for higher inventory costs when soft drinks need to be stored externally. These IPPS approaches take product families into account, which make the approaches willing to combine soft drinks of the same product family in the same production week.

production planning and control

In this model we used order data of the second half year of and simulated the SMD and HMT departments based on their real-life properties. We made a simulation model so that we can test the various methods and test their performance under the conditions of Company X.

Factors affecting production planning and control pdf

Picking in the general warehouse is not counted in this measure and that normally takes two days. The data for this system is available, although it is spread over multiple platforms, namely Baan and PFS. Value: The thesis will hold value for companies that fall under the MTO category defined in the thesis, given that they need to select a PPC system to improve production performance, and address any performance issues they may have. Therefore, we advise for the rules that are easy to implement and understand. We notice that currently planning and the control of load is only done on a weekly basis, at the tactical planning level. The first method is Workload Control WLC , in which each station has a limit for the amount of work that is on the shop floor for that specific station. During our research, we found three methods that according to the literature could work well at Company X. WLC is the system that shows the most promise. AP uses cost priorities and takes the constraints of the Syrup- and Packaging department into account to construct the production plan. After release, it takes on average more than five working days before the first operation is performed. Item Type:. Engineering and reengineering becomes part of the environmental factors complexity and dynamism that impact the applicability of a PPC method. The production plan is used by the production planner to construct the production schedule. We also conducted a sensitivity analysis on this combination of methods.

The second method is Kanban. This provides a better approximation of used changeover time in a week. Complexity represents numeral values that are known, such as Bill of Material BOMnumber of routings, product mix number of productsand number of converging or diverging routings.

Two remarks are needed here.

Production planning process

The data for this system is available, although it is spread over multiple platforms, namely Baan and PFS. Because the parameters of each manufacturing environment receives varying degree of attention in the reviewed literature, a case study would help pinpoint crucial environmental factors. In addition the Key Performance Indexes found in the MTO industry will be used as a base mark for PPC performance given the various manufacturing environments described. The research compares these planning approaches with the currently used planning approach AP. Besides the PPC methods, we also researched some priority rules, for determining the order in which we release the orders and in which order the repair department should handle the orders brought in. In this model we used order data of the second half year of and simulated the SMD and HMT departments based on their real-life properties. Login Hierarchically integrating the production planning and scheduling to optimize the production planning process of a beverage compan Horst, J. We notice that currently planning and the control of load is only done on a weekly basis, at the tactical planning level. Key PPC methods as suggested by Stevenson et al. Item Type:. In order to allow processing, generally two cards are needed, one for the loop of the previous and current station, and one for the loop of the current and next station. We also conducted a sensitivity analysis on this combination of methods.
