SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Computers & Chemical Engineering is primarily a journal of record for new developments in the application of computing and systems technology to chemical engineering problems. Several major areas of study are represented in the journal, including:
• Modeling, numerical analysis and simulation
• Mathematical programming (optimization)
• Cyberinfrastructure, informatics and intelligent systems
• Process and product synthesis/design
• Process dynamics, control and monitoring
• Abnormal events management and process safety
• Plant operations, integration, planning/scheduling and supply chain
• Enterprise-wide management and technology-driven policy making
• Domain applications (molecular, biological, pharmaceutical, food, energy, and environmental systems engineering)
Also, general papers on process systems engineering are welcome as well as emerging new areas and topics not covered above.
Articles published cover different aspects of the application of process systems engineering to one or more of the general areas listed above, including new applications of established methods, comparisons of alternative methodologies, descriptions of state-of-the-art industrial applications and significant developments in computing targeted at training/education. Reports of software implementation must feature novel uses of state-of-the-art computing technologies. Computers & Chemical Engineering publishes full-length articles, perspective papers, journal reviews, short notes and letters to the http://www.journals.elsevier.com/computers-and-chemical-engineering/editorial-board/editor.
Comments and Proposals: We are interested in receiving comments/feedback on this and our other journals and welcome publication proposals for books, electronic products, new journals and co-operation for existing journals.
