Which one of the following forecasting techniques is not suited for making forecasts for planning production schedules in the short range?

Which one of the following methods can be used for forecasting when a demand pattern is consistently increasing or decreasing?

Using the exponential smoothing method of forecasting, What will be the forecast for the fourth week if the actual and forecasted demand for the third week is 480 and 500 respectively and $\alpha$ = 0·2?

Consider the following statement relating to forecasting:

1. The time horizon to forecast depends upon where the product currently lies its life cycle.

2. Opinion and judgmental forecasting methods sometimes incorporate statistical analysis.

3. In exponential smoothing, low values of smoothing constant, alpha result in more smoothing than higher values of alpha.

Which of the statements given above are correct?

In a forecasting situation, exponential smoothing with a smoothing constant $\alpha$= 0.2 is to be used. If the demand for n^th period is 500 and the actual demand for the corresponding period turned out to be 450, what is the forecast for the (n + 1)^th  period?

A production line is said to be balanced when:

In an assembly line, when the workstation times are unequal, the overall production rate of an assembly line is determined by the:

A work shift is for 8 hours duration; 30 minutes lunch break and two 15 minutes (each) tea breaks are allowed per shift. If products are to go out after assembly at the rate of 60 per shift, and total assembly time content for a product is 42 minutes, then minimum number of work stations needed is:

Which of the following are the benefits of assembly line balancing?

1. It minimises the in-process inventory

2. It reduces the work content.

3. It smoothens the production flow

4. It maintains the required rate of output.

Select the correct answer using the codes given below:

A company has four work centres A, B, C and D, with per day capacities of 450 units, 390 units, 360 units and 400 units respectively. The machines are laid down in order A, B, C, and D and product has to be operated on all these machines for getting converted into finished product. The actual output turns to be 306 units per day. What is the system efficiency?

The routing function in a production system design is concerned with:

In production, planning and control, the document which authorizes the start of an operation on the shop floor is the:

Activities involved in production planning and control system are listed below:

1. Planning 2. Loading

3. Scheduling 4. Dispatching

5. Routing 6. Follow up

The correct sequence of these activities in production planning and control system is:

Consider the following statements:

Scheduling

1. Is a general timetable of manufacturing

2. Is the time phase of loading

3. Is loading all the work in process on

4. Machines according to their capacity

A soldering operation was work-sampled over two days (16 hours) during which an employee soldered 108 joints. Actual working time was 90% of the total time and the performance rating was estimated to be 120 percent. If the contract provides allowance of 20 percent of the total time available, the standard time for the operation would be:
