A manufacturer is studying a proposal to install an automatic device at one of its production operations. The device would perform the operation in exactly 0.5 minutes. At present, there is a (single server) manual operation with an average service rate of 60 per hour and exponential service times. The arrival rate is 50 products per hour and Poisson distributed. Each minute saved per product at the operation is worth $2. Assume that the total production for the year is 1,500.
1.What is the manual operations queueing model (M/D/1 or M/M/1)? (1 point)
2. What is the average time in the system in the manual operations (in minutes)? (2 points)
3. What is the automatic operations queueing model (M/D/1 or M/M/1) ? (1 point)
4.What is the average time in the system in the automatic operations (in minutes)? (2 points)
5.Calculate savings per product due to the automatic device? (2 points)
6.Calculate savings for one year due to the automatic device? (1 point)
7. If the device costs $10,000, should the device be installed, i.e., would it offset its cost in one year (Yes/No)? (1 point)

Ace’s Fast Food and Beverages Inc. realized that they were losing customers and orders due to various delays and errors. In order to get to the root cause of the problem, they decided to track problems that might be contributing to customer dissatisfaction. They track complaints from diner satisfaction cards that are turned in at each table. The following list of the problems shows their frequencies of occurrence over a six-month period. Construct a Pareto chart to analyze this data and include a copy of this chart with your assignment. What recommendations could you make to reduce errors and increase customer satisfaction? In other words, what problems would you focus on first?

High uncertainty avoidance suggests need for job security, low uncertainty suggests motivation by risky opportunities. High power distance suggests motivators in boss-subordinate relationship, low power distance suggests motivation by teamwork and peers. Individualism suggests motivation from opportunities for individual advancement and autonomy, collectivism suggests appeals to group goals and support and masculinity suggests people are more comfortable with traditional division of work, femininity suggests looser boundaries, flexible roles. Mexico’s emphasis on family means that loyalty and commitment to family and friends often underlies personnel decisions. This emphasis has many implications for structuring motivational initiatives. For instance, turnover and absenteeism can be very high, with “family reasons” being most commonly cited for absenteeism and for failing to return to work. For Mexican males, the value of work lies primarily in its ability to fulfill culturally imposed responsibilities as head of household and breadwinner rather than to seek individual achievement. Paternalism is expected, and bosses are often viewed as father figures whose role is to take care of workers. Likewise, employees expect managers to be authoritative. If not told to do something, the workers will not do it, nor will they question the boss or make any decisions for the boss. Many Mexican factory workers doubt their ability to personally influence the outcome of their lives. They attribute events to the will of God, luck, timing, or relationships with higher authority figures. Corrective discipline and motivation must occur through training examples, cooperation, and, if necessary, subtle shaming. It is a mistake to directly insult a Mexican. Thus, one must appeal to the pride of Mexican employees and avoid causing them to feel humiliated. Given that “getting ahead” is often associated with outside forces, motivation and reward systems become difficult to structure. For the most part, motivation through participative decision making is not as effective as motivation through more autocratic methods. Mexican workers expect authority will not be abused but rather will follow the family model in which everyone works together in a dignified manner according to their designated roles. Any event that breaks this harmony or seems to confront authority, will likely be covered up. For example, a supervisor may hide defective work. Maslow’s higher-order needs (self-actualization, achievement, status) are not high on many Mexican’s lists of needs because of a context of continuing economic problems and a relatively low standard of living. Additionally, economic reforms and the peso devaluation make money a key motivational factor. Fringe benefits also are important. Benefits that help to manage family-related issues are positive motivators for people to at least show up at work. Thus, companies often provide on-site health care facilities for workers and their families, nurseries, free meals, and even small loans in crisis situations. Company buses may be provided to minimize absenteeism and tardiness.

Introduction
The course project is a series of elements where you will examine the current standing of an organization’s compensation system. In the final element of the training program, you will provide recommendations to the organization on how the compensation program can be improved.
Directions
Students will conduct an analysis on the current state of the compensation system and address the current pay structure used. Reference should be made to job-based and person-based structure. Analysis should reference sources of information for job analysis, job evaluation, pay design, and pay levels.
The body of the paper will be 4-5 pages. This does not include extraneous pages like title page, reference page, appendices. APA formatting standards are required. A minimum of 5 scholarly resources need to be used. An example of a scholarly resource can be an interview with an HR professional or a peer reviewed article from a Park University Library Journal Database. Course materials and personal experience do not count. A formal third person tone is required.
Supplemental information (e.g. worksheets that are currently being used) can be presented in Appendices but do not count toward the body of the paper.
Note: Recommendations should not be made at this point – you will make these in Unit 8. This is an analysis of current standing. Keep in mind however, if an organization doesn’t have a set structure, the paper doesn’t end at that point. Student needs to include a discussion of the different methods that could be used. Again, recommendations will be made
Please also include at least 5 references
