这句话关键的问题是没有动词.
Distribution management is aiming for improving customer satisfaction through raising the quality of service,with lower distribution cost,better planning,organization,coordination and better control of distribution activities.
这句话太长了,可以考虑分成几句.
The main purpose of distribution management is to improve customer satisfaction.Necessary means to achieve that are:1) raise the quality of service; 2) lower distribution costs; 3) more efficient planning,organization,and coordination; 4) last but not least,better control of distribution activities.
这样表达比较清晰.
