Michael Appleton was removed from the Ewood Park hotseat after just 67 days, joining Henning Berg and Steve Kean in being shown the door by owners Venky's this campaign.
But Singh has told fans they remain committed to turning the club's fortunes around.
"I would like to assure the fans that everything possible is being done to make the club enjoy long-term stability," Singh told BBC Sport.
"In football, you have to set long-term plans. Unfortunately, situations sometimes happen where you have managers with differing philosophies and this can cause the transition period to take longer than expected.
"We all know the transition period will end very soon and the fans will start enjoying their football again.
"The ambition is to get the club back on its feet and achieve what all club owners would like to achieve. So you can take it from me the owners are 100 per cent committed."
