It is broader than operations analysis. 6 Evolution and Scope of Methods Engineering Initial research (late 19th century) - Frank Gilbreth: Motion study Scientific management (late 19th century-early 20th century)- Frederick W. Taylor: Motion and time study (first principle of the five principles) Primary concern: manual physical labor Today: methods engineering is applied to areas such as indirect labor, logistics, service operations, office work, and plant layout. 7 Methods Engineering Can be divided into two areas: 1. Methods analysis 2. Methods design 8 Methods Analysis Concerned with the study of an existing method or process break the method (process) down into work elements or basic operations examine the details of the elements: a systematic (methodical) search to improve the process This involved checklists of questions and suggestions for improvements Objectives : Eliminate unnecessary and non-value-adding work elements Combine elements and operations Rearrange elements into more logical sequence Simplify remaining elements and operations 9 Methods Design Concerned with either of the following situations: 1.Design of a new method or process Required for new product or service and there is no existing precedent سابق Method must be designed from scratch بدأ من الصفر, using best existing practice أفضل الممارسات القائمةfor similar operations 2.Redesign of an existing method or process based on a preceding methods analysis 10 Systematic Approach in Methods Engineering 1. 2. 3. 4. 5. 6. Define the problem and objectives Analyze the problem Formulate alternatives Evaluate alternatives and select the best solution Implement the best method Audit the study (مراجعة الدراسةfollow-ups) 11 The Techniques of Methods Engineering The following techniques are mostly accociated with the analysis step in the methods engineering. o o o o o o Data gathering and statistical tools Charting and diagramming techniques Motion Study and Work Design Facility Layout Planning Work Measurement Techniques New approaches 18 Charting & Diagramming Techniques They are available mainly for collecting, displaying and analyzing data Network diagrams Traditional industrial techniques Operation charts Process charts Flow diagrams engineering Other (alternative) diagrams Block diagrams Process maps charting 19 Motion Study and Work Design Concerned with basic motions of a human worker while performing a given task 17 basic motion elements, like reach, grasp, move, release “Principles of motion economy”- guidelines for work design o Use of human body in developing the standard method (e.g., design the work so that both hands are fully utilized) o Workplace layout o Design of tooling used in the task 20 Motion Study and Work Design -Objective Unnecessary motions can be eliminated. Some of the combined. motion elements can be The method can be simplified. 21 Facility Layout Planning Facility layout refers to: o Size and shape of a facility o Arrangement of the different departments and equipment within the facility The layout plays an important role in determining the overall efficiency of the operations Problem area includes: o Design of a new facility o Installing new equipment, retiring old equipment o Expanding (or contracting) an existing facility 22 Work Measurement Techniques Four basic work measurement techniques: 1. Direct time study 2. Predetermined motion time systems (PMTS) 3. Standard data systems 4. Work sampling They can be used in methods engineering to make improvements in the work methods 23 Basic Data Collection & Analysis Tools 1. Histograms 2. Pareto charts 3. Pie charts 4. Check sheets 5. Defect concentration diagrams 6. Scatter diagrams 7. Cause and effect diagrams 27
