Search problem
Transfer problem
How can we mitigate
search and transfer problems
in a systematic way?
Network structural approach
Q1. How can we measure
    the collaboration performance
    of a network?
Q2. How can constraints of
    collaboration network optimization
    be quantitatively modeled?
Q3. How can we optimize a network
    and how much is the performance
    improved by the optimization?
1. Measurement Development
SPI = Search Performance Index
TPI = Transfer Performance Index
2. Defining Constraints
Fixed total strength of the network
Fixed total number of links in the network
1) "link-based algorithm"
   Moving edges to find
   higher performance index

2) "strength-based algorithm"
   Redistributing strengths
   between two edges
3. How to Optimize
By link-based algorithm
1) One strong cluster as information intermediary emerged.

2) When maximizing Search Performance Index,
   the central cluster got strong pointings from all units.
By strength-based algorithm
Strength becomes polarized.
How much were the performances improved?
Search
Transfer
Implications
1) Search and transfer problems can be improved simultaneously.
   It's not a perfect trade-off problem.

2) Have a central unit or cluster playing a role of information intermediary.

3) Make strong ties stronger, weak ties weaker.
   Do not waste organizational effort to strengthen weak ties.
   Rather, focus on the strong ones.
