Lab # $9$: MOST

Objective:

To use the MOST tables to determine the time standard for the given operation.

Discussion:

MOST is a predetermined time system, which allows the analysis of any manual operation and several equipment operations. The MOST concept uses fundamental activities, which are combinations of motions, to analyze movement of objects. The basic patterns of movements are described in sequences. MOST stands for Maynard Operation Sequence Techniques. Time values are expressed as index values, which represent a range of times. These indexes are then assigned to the fundamental activities to allow analysis of operations.

MOST is based on the principle of work, which as defined in physics is "force X distance". This concept says that time is allowed only if work is done, that is when objects are moved.

Time units used in MOST are based on hours and parts of hours called time measurement units $($TMU$).$ One TMU is equivalent to $\mathrm{.}00001$ hours. $27\mathrm{.}8$ TMUs $=1sec.$

MOST technique comprises of the following basic sequence models:

The General Move Sequence$-$ for the spatial movement of an object freely through the air. Examplewalk three steps to pick up a bolt from the floor level, arise, and place the bolt in the hole.

The Controlled Move Sequence$-$ for the movement of an object when it remains in contact with a surface or is attached to another object during the movement. Example$-$ engage a feed lever on a milling machine.

The Tool Use Sequence$-$ for the use of common hand tools. Example$-$ the use of a wrench.

Manual Crane Sequence $-$ applied when moving objects with a manual crane

Advantages of MOST:

Time reflect a $100\%$ performance level.

MOST is fast to apply.

Easy to understand and learn.

Consistent results.

Uses of MOST:

Determine the total labor cost of the product.

Determine the number of production workers required.

Determine number of machines required.

Determine the delivery times for the produced product.

Determine the overall production schedule.

Set realistic production goals.

Know the actual cost of production.

Introduction

Brief introduction to MOST and to the activity to which you applied MOST. Apply MOST analysis to the operation you performed time study in Lab $5($Two hand chart$).$

Your MOST analysis

For each activity to which you apply a MOST sequence model, provide a brief description and include any assumptions you made in selecting the particular sequence model or parameter index values.

Comparison of MOST analysis and your time study analysis

Discuss any significant differences between the two analyses
