Kanban
Healthcare Clinic
A revolutionary technique in healthcare
using kanban principles allows exception speed
to service. This model shows the techniques used
to achieve sub 1 hour cycle times even when three
or more services were required.
Many of the principle used are explained in detail
by activating the layers. Each layer explains
a modeling concept.
A model of a current 'central
dry cleaning plant' located in Central Texas.
They originally had five retail drop stores including
one store attached to the plant plus two routes
as shown in the light blue colored Collection
Phase. The 'central plant' was processing approximately
6700 garments in a five-day week and wanted to
know where the bottlenecks would occur if they
added two more retail outlets and one more route
with the expectation of the volume rising to over
10,000 garments per week. The owner wanted to
increase his garment processing count without
incorporating any overtime. For this reason, the
concept of 'LEAN Thinking' was applied to this
model.
This model provides an illustration
of the different dynamics of JIT vs. Batch Processing
in the context of a service system.
The model captures the processses for telephone
repair in a large metropolitan area. Calls requesting
service arrive at the Automated Call Center according
to time of day, day of week, and service type:
Out of Service and Affecting Service. The repairs
are screened in three phases to determine whether
a repair service technician must respond. If so,
a Repair Ticket is generated and sent to the Repair
Center.
