TOPIC

Optimal Allocation of Production Lots to Surface Mount Technology Lines

Abstract:

In the electronics manufacturing industry, Surface Mount Technology (SMT) is the primary technique for assembling electronic components into circuit boards. Effective management of SMT lines relies on making the best use of capital intensive resources to produce circuit boards under the pressures of a highly variable environment with regards to customer demand, component availability and product specifications. This presentation examines how to optimally allocate a set of orders for circuit boards to the existing manufacturing lines in an SMT facility.

In this research a mathematical programming model is developed to decide which orders should be built on which SMT lines. Measures are developed that aid in comparing production losses and efficiencies between different model runs. The ability to move component placements from one machine type to another is investigated and is shown to yield performance improvements in terms of reduced makespan.

About the Speaker

Ryan Warrington is currently an Engineering Instructor in the Dept. of Math, Physics, and Engineering at Mount Royal College (MRC). As well, he is the Director of Quality Control/Design Engineer with Tech Works Engineering Inc. He graduated in 1998 with a B.Sc. and in 2003 with a M.Sc., both from the Dept. of Mechanical and Manufacturing Engineering at the University of Calgary. Building on his work at Celestica Inc., Ryan’s graduate work focused on production planning for electronics manufacturers; specifically in optimal allocation of production lots to surface mount technology (SMT) lines.

Ryan Warrington’s work at MRC has been focused on the development of real world design courses. He currently leads the first year engineering design and communication courses, which place 150 students against design challenges sourced from the local business community. This set of courses, developed in conjunction with the U of C, employs an entirely new and multi-disciplinary approach to the teaching and learning of design, together with written, oral and visual communications.

Ryan was a founding member of the Formula SAE Design Competition Team at the U of C, which annually designs and builds a racecar for competitions held in Detroit, Michigan. After five years of design experience with the team, tried and tested methodologies are now applied to his work with Tech Works Engineering Inc., a Calgary-based automotive component design company. Ryan’s involvement with motor sports also continues with several local wins and a 2nd place finish at the Canadian National Autoslalom Championships in August.

Ryan is member of APEGGA and the Engineering Society for Advancing Mobility in Land, Sea, Air, and Space (SAE).
