TOMAS - EFFICIENT
Inventory management is important because:
Hence, there are two conflicting requirements.
Optimal inventory management policy is the one that makes compromise to
satisfy both requirements, with the least total costs, consisting out of:
The purpose of inventory
is to amortize discontinuities of demand for
materials, products, tools, spare parts etc. i.e. to provide for uninterupted
flow of bussines processes. Therefore, the bigger inventories, the better
for stability of bussines processes.
working capital. Therefore, the lower inventory, the better.
TOMAS offers various possibilities:
costs of having inventory (capital, space,
handling, deterioration etc)
costs of not having inventory, when needed
(interupted production, late deliveries, loss of goodwill etc)
ordering costs (procedures, transport, incoming
control, setup times in production etc.).
Follows the short description of what TOMAS
offers in this area.
to find the most adequate inventory management
to support these policies in a daily work
to analyze inventory transactions and state,
i.e. to pinpoint problem areas.
DEFINING INVENTORY MANAGEMENT
Planning of sales,
production, maintenance and purchasing -
enables finding dynamics of inventory requirements.
simulations - various hypothetical
ordering policies could be simulated and choosen the most adequte one.
This is done by so called Monte Carlo stochastic simulation method. The
user gives the data on expected demand quantities, ordering costs and delays
and TOMAS delivers data on the structure of costs for simulated policy.
of ordering policies, based on actual consumption in previous
period and estimation of delivery time for ordered items.
check of each item of inventories is done daily and, where necessary, TOMAS
generates purchasing order or work order, for appropriate quantity.
display on the screen:
These data are displayed each time one enters
purchasing or sales order or production work order or just checks inventory
status, i.e. each time when ordering action might be initiated.
quantity on hand, total in all warehouses
total undelivered quantity to buyers
or from vendors
quantity in unfinished production.
Analysis of inventory
transactions and state:
Summary of inventory transactions values
and state, by warehuse - 1 page or only few lines display state of
ABC inventory value analysis, by product
- usualy 5 % of items carry up to 90 % of total stock value.
ABC inventory transactions value analysis
- indicates what materials or class of materials, what partners or class
of partners, have biggiest part in sales, purchasing, or production.
Material transactions analysis by characteristics
of products or partners - detailed or summary report, for fully or
partialy (generic) defined characteristics.
Comparison of quantities and values by
period for sales, purchasing, or consumption, by material, class of
material, partner, class of partner etc.
List of inventory items for which:
is bigger or smaller then user specified
value on hand
value of input
value of output
last input date
last output date
For example, list of inventories with:
turnround coeff. < 6
and with no output in last 30 days.
Inventory status of "critical items",
i.e. below minimum or above maximum.
These options enable
the user of TOMAS:
Graphic display of inventory transactions
value flow in time, by warehouse and for the organization as a whole.
to find most adequate ordering policies
automatic ordering, in accordance with
prompt and permanent insight into inventory
transactions and state, pinpointing problem areas
alltogether, full control of material flows
and very efficient inventory management.
