Broker model

The broker model, whereby the intermediate agents apparently shield the actual source from the destination and often act as virtual sources down the line, may be thought of as an extreme case of the supply chain. In such a scenario, the service quality constraints are to be met by all the agents in between. 

Indeed, a number of incumbent players have started to estabhsh onhne marketplaces, by themselves or together with newcomers, following a model set up not by chemical companies but by Internet brokers such as Omnexus or Elemica (see also Chapter 7). 

Finally, more new players will start to enter the market. These may be either incumbents experimenting with new business models and new market spaces such as DuPont, or there may be new players. We basically see three types of new entrants emerging functional speciahsts (i.e., infrastructure providers such as Vo-pak), market brokers such as CheMatch or Omnexus, or financial investors such as CVC and The Sterling Group. 

The framework IR spectra were recorded in a Nicolet (60 SXB model) instrument using KBr pellet technique. 1 l"Sn MAS NMR spectra were obtained at 111.82 MHz on a Broker MSL-300 NMR instrument. Typically around 3000 transients were signal averaged before Fourier transformation. The chemical shifts were referenced externally to tetramethyltin.

The real issue within the production environment is the transfer of various object data between applications. What is required is some sort of "object broker" or object management mechanism (OMM). This mechanism effectively handles multiple objed models it converts them into a common format that can be successfully transferred between various applications and then be reconstructed at the other end. 

This is the main difference between emerging solutions and the standard solutions of the 1990s. Although some form of bespoke interface may still be required to translate a particular data format and protocol to an object model, once this is developed, the resultant data are then available to all other users via the "object broker".

In contrast to our approach, pub/sub models [14,13,4] require message broker nodes which conduct the message reception and forwarding mechanism. The notion of message brokers represent like super peers in hybrid P2P systems potential weak points in the system. 

The supply chain power structure is one of the major unique factors. The concept of a broker is adopted here (Ross et al. 1998). The supply chain ctMifiguration problem is formulated substantially differently depending on relatitniships between the organizations involved, thereby influencing parameters included in the model and considered performance measures.
