JobTime Systems has performed a variety of consulting services projects that
involve detailed scheduling related to critical company issues and decisions at
some of the nation's leading companies. These cases illustrate the variety
of problems and applications JobTime has been able to successfully model and
solve. Each example typically includes the following steps:
Definition of a critical issue demanding a detailed scheduling component,
Analysis and resolution of the key business issues involved, and
The continued use of the application often leads to detailed shop scheduling, for a number of years thereafter.
Scheduling detailed maintenance operations on aircraft engines to
verify a policy on level-of-spares, designed to protect against
unacceptable stock-outs, while also controlling the investment in costly
spare aircraft engines.
Demonstrate the ability to
assure the on-time delivery of nuclear fuel replenishment at
client power plants. Verification included drill-down of finite
scheduling in units per day of each sub-assembly component involved in
the fuel assembly.
Verification of proposed major changes in purchasing
policy to synchronize material purchases of smaller and more frequent
order quantities, more
closely tied to the timing of the scheduled material demands in
Sizing casual labor pools ("Diverted Labor") to
assure steady and stable employment, and to reduce erratic peaking of
labor demand. Multiple resource constraints reflected the
variety and configuration of packaging labor types which varied with the
product being packaged.

Establish the feasibility of Just-in-Time manufacturing
for an Assemble-to-Order and Engineer-to-Order Environment manufacturing
power transformers. View Article (PDF Format).
Accurately model CD-ROM extrusion, surfacing, printing and
packaging, in a fast turnaround cycle times of 24 to 72 hours.
View capacity load, and predict daily shipments, and provide available
to promise capability. Add equipment to balance work loads.
Flexible Machining Systems (FMS) present a difficult
challenge for finite scheduling. These flexible machines can
alternate single parts from a variety of pending orders, in round-robin
fashion. Maquinados inventory of over 100 such systems makes
it one of the largest such facilities in the world. The challenge
was to demonstrate the capability to accurately estimate each order's
start and completion date in a complex FMS environment.

To fabricate the components of an oil drilling platform, a
significant volume of repetitive steelwork is required. Demonstrate the
ability to accept data from a major project management system, and
finite schedule detailed steel shop operations, uploading both start and
finish dates of each activity back into the project management
Inductoheat makes induction heating machines to
harden parts mostly for the automotive industry. View Article
(PDF Format). Each induction machine is configured to
deliver induction hardening to the perimeter of conductive metal parts,
typically for automotive applications.
Laser Optics, Inc. polishes mirrors for special laser and
optics applications, such as the Hubble Telescope. By
proportions, if a 5 meter diameter mirror were enlarged to a 20 wide
disk, the maximum deviation from perfect flatness could be no larger
than a football on its side.
Hill Parts manufactures spare parts for the
poultry processing industry. These parts include blades, and
processes to automate the preparation of poultry products.
Customers include leading poultry processors across the world.
Rayton Packaging makes plastic bags for
grocery stores and food packaging applications. This application
requires careful setup management for graphics as well as production
Coulter Forge & Steel creates custom rings, and
other forged products. Key parts are forged rings which are used for
magnetic applications to support technologies like MRI machines
and semiconductor fabrication.
Bosch Automation Products makes components for automated
assembly lines, especially to support high-tech circuit fabrication
and assembly. Parts are machines on multi-pallet Flexible Machine
Systems to concurrently make parts for multiple client work orders in
round-robin fashion, which created a challenges for scheduling, which
has been solved by JobTime Systems.
Nova Chemicals Technical Research and Development Lab uses
JobTime so schedule the fabrication and testing by over 250 plastics
specialists. Materials are fabricated using client-specific
resins, and each client's test materials are subjected to a battery of
tests across multiple laboratories.
Central Shops was one of the world's largest job shops,
with over 500 employees, supporting the needs of a variety of Cominco's
mining operations in the Canadian province of British Columbia.
Pending the acquisition of a major ERP system, the challenge was to
demonstrate the feasibility of detailed finite scheduling across
all work centers in the entire Central Shops on a PC Platform.
