The paper considers the concept and importance of supplylogistics as element in improving storage, supply and transportof goods in big cities. There is always room for improvements inthis segmenl of economic activities, and therefore continuousoptimisation of the cargo flows from the manufacturer to theend user is impor1a11t. Due to complex requirements in thecargo supply a11d the 'spoiled' end users, modem cities represe/ll great difficulties and a big challenge for the supply organisers.The consumers' needs in big cities have developed over therecent years i11 such a way that they require supply of goods severaltimes a day at precisely determined times (orders are receivedby e-mail, and the information transfer is therefore instantaneous).In order to successfully meet the consumers'needs in advanced economic systems, advanced methods ofgoods supply have been developed and improved, such as 'justin time'; ''door-to-door', and 'desk-to-desk'. Regular operationof these systems requires supply logistics 1vhiclz includes thetotalthroughpw of materials, from receiving the raw materialsor reproduction material to the delive1y of final products to theend users.

Manufacturers and traders have always had to handle themanagement of supply chains. H01vever, this concept in itspresent meaning has only gained major importance in therecentyears. This is the result of linking supply chains with newtechnologies. The supply chain starts and ends with the endbuyer. The essence of supply elwin management is awarenessof the buyer's wishes and rapid delive1y of the required productsor se1vices. Supply chains play an exceptionally important roleroday. A common strategy for joint projects has ro be workedout wirh partners. In orderro achieve this, a lziglz degree of trustmust exist between them. Partners from various disciplines arenot competitors, but complement, and co-operate with eachother. In cold chains that ensure that perishable goods cover theproducer-consumer route in rlze shortest possible time, co-operationand trust are of key importance since only companies ableto provide the buyer with the right product at the right place andat the right price are successful in the market.

The compound distribution is of interest for the study of inventoryproblem, since it provides a more flexible description ofthe stochastic properties of the system compared to many otherapproaches such as renewal processes. However, due to the difficultiesof obtaining analytical results for the compound distribution,such a type of study is usually limited to searching for agood approximation for replacing the complex model. This paperinvestigates the possibility to extend a previous stochastic inventorymodel to cover a compound demand process. Transformmethods again play an imp01tant role in the analysis forcapturing the stochastic prope1ties of the compound distribution.

This paper follows up a previous study for optimising a production-inventory system when external demand is stochastic.A modified stock-out function is presented to cover more generalsituation when cumulative production may be a continuousvariable. Optimisation equations are further investigated,including the sufficient conditions for optimisation.

The external supply of logistics se1vices is part of a trend towardoutsourcing non-core logistics activities. The scope ofthird-party logistics may range from a relatively limited combinationof activities (e.g. transportation and warehousing) to acomprehensive set of logistics se1vices.The authors first discuss the characteristics of business logisticsin manufacturing indusfly, to be taken into account inlogistics outsourcing. They particularly point out the motimtionsfor logistics outsourcing, the possibilities of outsourcing,as well as supplier selection. Finally they analyze the outsourcingin the reverse logistics.
