on "Types of traffic Party objects Operations"
Initial data
Choose the individual data of the following limits:
- The volume of production of n = 2 pcs.
 the size of the transfer party items for p = 1 .;
 norm piece of time on operations: t1 = 2 min / pcs .; t2 = 4 min / pcs .; t3 = 3 min / pcs .; t4 = 2 min / pcs.
Required
1. Plot the processing party objects to transactions in different types of traffic Party objects Operations: serial, parallel, serial to parallel (mixed).
2. Determine graphically and analytically T - the duration of treatment of the party items for all transactions in different types of traffic Party items on operations and other parameters of graphs, such as mikroprostoi on operations in parallel as the motion of objects on party operations.
3. Outline the advantages and disadvantages of each type of traffic Party objects for operations.
4. Specify the scope of each type of traffic Party objects for operations.
5. Select the best example for your kind of traffic Party items on transactions and justify the choice.
6. Specify the assignment of the selected type of traffic Party items on transactions, particularly where and what it is used.
7. Determine the type of movement for the selected batch of objects for operations calendar start and end dates batch processing items on each operation, start your own target date shift (eg 8 o´clock in the morning).
on "exploded schedule start
and release parties objects "
Initial data
Choose items for A and B values of n, R, and the following Tc their limits: n = (20 ÷ 60) pcs .; R = (3 ÷ 6) slave. days .; Tc = (2 ÷ 8) slave. days. And for the object A to be R ≥ Tc, and for the subject in the: R <T *.
Required
1. Build an exploded schedule start and release the parties objects on the selected planning horizon (to justify the planning horizon) in the form set out in Table. 2.
2. Snap exploded schedule to the actual calendar (excluding public holidays) and calendar to determine the launch date and the release of each batch of items.
3. Specify the scope and purpose of exploded schedules where and what they are used.
on the theme "Building Exploded view of operational-
calendar schedule "
Initial data are given in the Table. 6.
Required
1. Ask yourself the technological route processing operations on objects. For example:
 for the object A: T-C;
 for the subject B: W-T;
 for items with a: C-O;
 for the object D: W-C;
In the future, these routes can not be changed. The route may not be all of the Table. 1 operation.
2. Of the total number of subjects in ways to start the process, which is equal to I !, where I - the number of names of objects (for example, the number of ways to start the treatment of subjects is 4! = 24 option), randomly select two options, for example:
Option 1: A -> B -> D -> C;
Option 2: D -> C -> B -> A.
3. To set a specific input data of the limit values given in Table. 1.
4. Calculate the length of processing batches of items from operations tnij formula

where i = - Subject of the index; j = - index operation; ni - the batch size of items of i-names, pcs .; tij - rate piece processing time the subject of i-names in the j-th operation, h / pcs .; γj - the coefficient of performance of norms of the time on the j-th operation; SCI - the length of shifts (8), h / cm.
5. Build CNG for each of the two ways to start the processing of objects in the form set out in Table. 2.
Table. 2 index of the part number indicates the number of transactions, ie, A2 - Processing party objects names And on the second transaction. Transfer Time Party objects to the operation for the operation in the construction of CNG is not taken into account. CPG is based on the time required to process a batch of objects of all kinds (Tts.s).
6. CNG indicate Tts.s - the total duration of the production cycl
