This paper discusses the initial efforts to implement simulation modeling as a visual management and analysis tool at an automotive foundry plant manufacturing engine blocks. The foundry process was modeled using Pro Model to identify bottlenecks and evaluate machine performance, cycle times and production data (total parts, rejects, throughput, products/hr) essential for efficient production c...

A portable assembly language provides access to machine-level features like memory addresses, machine words, code addresses, and modulo arithmetics, like assembly language, but abstracts away differences between architectures like the assembly language syntax, instruction encoding, register set size, and addressing modes. Forth already satisfies a number of the characteristics of a portable ass...

This paper considers an optimization problem arising in the automated manufacture of printed circuit boards. An essential part of this problem is to determine good component pick and place sequences as this can reduce the overall assembly time significantly. This component placement sequence problem can be modelled as a Travelling Salesman Problem, however complex machine and process specificat...

The portal channel is a key component in the life cycle of bacteriophages and herpesviruses. The bacteriophage P22 portal is a 1 megadalton dodecameric oligomer of gp1 that plays key roles in capsid assembly, DNA packaging, assembly of the infection machinery, and DNA ejection. The portal is the nucleation site for the assembly of 39 additional subunits generated from multiple copies of four ge...

high yield and safety engagement. This paper describes the design of different parts of an automated high speed machine to assemble the parts of roller clamps. The roller clamp robotic assembly system performs various processes in the assembly line which include clamp body and roller feeding, inserting the roller into the clamp body, and dividing the rejected clamp and successfully assembled cl...

This paper proposes a heuristic algorithm, called list-based squeezing branch and bound algorithm, for solving a machine-fixed, machining-assembly flowshop scheduling problem to minimize makespan. The machine-fixed, machining-assembly flowshop consists of some parallel two-machine flow lines at a machining stage and one robot at an assembly stage. Since an optimal schedule for this problem is n...
