• time requirements of tie-in technology (if it concerns one direction, regularity or
irregularity, continual or cyclic transport, speed of a supply at the beginning and of a
removal at the end of the transport line, and so on),
• used mean of transport at the entrance or removal of the store; it means – if the
supply to the store is provided by a railway or a road transport (or some other
transport) and which specific means of transport are used,
• floor yardage demands; demands for the width of transport and manipulation alley.
If the technical or technical-technological sides are evaluated usually the first
selection could be made, but it has to be completed by evaluating some others criteria.
The economic criteria of selection deals mainly with a providing price (capital
expenditure), depreciation rate, induced costs, maintenance and repair expenses, labour costs
for operation... Quite important economic indicators (besides those already mentioned) from
the point of view of selecting an appropriate mechanization facility are operation expenses for
a manipulation unit per given space of operation time (e.g. €.t -1 ) and year´ s converted costs
€.year -1 ), which summarily express investment and operation costs.
It may happen that after considering all the economic criteria, two or more facilities
appear as equally convenient[4]. Thus we need to consider also some other criteria, which
cannot be specified as accurately as the technical and economic ones.
The other criteria of selection are usually of an indirect economic influences´
character. Some of them:
• provision of safety of material during the storage and manipulation,
• flexibility of projected facility in case of possible change in tie-in technology or its
adaptation to automation,
• safety of work and operation of facility,
• anticipated utilization period,
• other, e.g. ecological concerns and so on.
CONCLUSION
There are apparently tendencies to, as much as possible, harmonize and cooperate the
elements in the area of stores and their technical and technological equipment projection and
planning. Nevertheless, it is very important to optimize the final systemic projection of
storage according to individual needs of concrete customer.
