Solution of Bottleneck problem - Assignment Example

Solution of Bottleneck problem In the current world, people find themselves caught up in problems that no one had a clue that they would occur. Consider a situation, in a process, where stagnation of a process occurs as a result of a delay in one section in the same process. The problem is common in production lines, communication sectors, bank, and public areas, queuing areas including election periods, just to name but a few. It was observed that this landed people into headaches, and if not dealt with in time, they are forced to wait until the delay is over, which results to a bunch of problems. However, there are always alternatives that can be embraced to avoid such ups and downs. These actions could even call for an evaluation of the entire process, and once a section that is responsible for the stagnation is established, one can always know what to do to correct it. Such a problem was encountered in one of the buildings, Annex Building entrance, and below is how the irregularity is contained effectively, after close examination of the problem. The doors to Annex building, used on daily basis by different people ranging from workers who have offices in the building, hundreds of teachers and students with classes there, and others wishing to access facilities such as library and food courts. This large number of people flocking into the building further bring into consideration the aspect of convenience which should be paramount for ensuring minimum time loss and for controling excessive crowding at the doors. As expected, the doors to this building should be easy and straightforward to use in order to ensure that there are no inconveniences that arise when anyone wishes to access the building. Though the process sound so simple theoretically (just grasping the handle, pulling/pushing the door open and proceeding through), it is cumbersome when practically done. Numerous factors cause people to halt interactions until they can get someone to ask for assistance. These factors include overcrowding, usability of the arm, people’s baggage loads, and cases when individuals with wheelchairs experience problems at the doors. In a research carried out in the same building, it was found that most people find the doors extremely hefty and difficult to open, commonly experienced when moving a lot of or bulky items. Additionally, there is no automatic opening of the doors for people with wheelchairs. Finally, the doors are too small compared to the opening that creates a bottleneck effect, bringing about overcrowding. The process was illustrated in the flow chart on the next page. It outlines the procedure for getting into the Annex building, starting at the instant one approaches the door up to when the time they go past the same. The method involves; a. Going straight to the doors b. If one is in a wheelchair, ask for assistance. Otherwise, reach for the handle c. If one can use their arm, they push the handle, and if they cannot, they ask for help and proceed as well. If a way of relieving some of these procedures is established, such as creating a smooth entrance, it will be of help to various the individuals using this facility. Those with inabilities of using their arms or on wheelchairs will thereby be taken into account. The new design should involve a simplified procedure that will enhance an easy way of getting into the Annex building. As can be observed from the flow chart above, when one approaches the Annex building door, those with wheelchairs and the ones incapable of using the arm have to ask for assistance. It is evident, therefore, that such individuals are inconvenienced, and such is a problem that should be addressed. Solution to the problem Replacement of the doors with those that slide automatically is a good way to eliminate the usability problem as well as to allow wheelchair access and thereby expand the usable space. Secondly, the entrance doors can be shifted forward, which will help combat the problem of difficulties while opening the doors and also improving doorway size, eliminating opposing flow problems and bottleneck. It is possible to do this because the entering traffic is split, and they exit through two separate doors. Below is the new outlook of the new flow of events outside the doors of Annex building. (Seyfried et al., 2010) Cleary it is notable from the new architecture that the process is simplified and made easy. One only needs to approach the door, whether in a wheelchair, capable of using an arm or not and get close to the sensor and the door opens automatically and they proceed through. A request for permission To the manager, writing to ask for permission for the following changes to be put in place for the Annex building doors, kindly include all that apply. This change can be used as an alternative or a parallel system that is considered helpful. Replacement of the current door with those that slide automatically Shift the entrance doors forward The new changes will bring about a complete revolution of inconveniences currently experienced at the doors by; Eliminating the usability problem and allowing wheelchair access hence expanding usable space getting rid of problems arising when opening the doors widening the width of the door entrance eliminating opposing flow problems and bottleneck that results These adjustments will lead to further advantages such as saving time, which could have been wasted as a result of overcrowding at the doors. The effectiveness of the building will also be enhanced. Reference Seyfried, A., Boltes, M., Kähler, J., Klingsch, W., Portz, A., Rupprecht, T., ... & Winkens, A. (2010).
